Abstract: PROBLEM TO BE SOLVED: To obtain a device for a wavelength division-multiplexed optical communication network of an independent transmission form by separating identified spectrum components from another spectrum component at the time of dropping through the use of a single optical switch of (1×1) or (2×2) singly or incombination with another optical switch. SOLUTION: A wavelength selectivity adding-dropping multiplexer(WSADM) receives a WDM signal 2 with N-number of spectrum components (namely wavelength) λ1 -λN and removes (namely drops) a first selected spectrum component λ1 from these plural spectrum components. In addition, a second selected spectrum component N+1 is added to these plural spectrum component. In case when a first spectrum component λ1 is dropped, the second spectrum N+1 is added for exchanging this dropped spectrum component. The spectrum components can be added or dropped.

Abstract: PROBLEM TO BE SOLVED: To provide a method for forming liquid drops below a micron size. SOLUTION: A micropipette 4 having a bore below the size of the liquid drops to be formed is connected to a system for applying a positive pressure and, in some cases, a negative pressure, on the inside thereof. The front end 6 of such micropipette 4 is brought into contact with the liquid. This liquid is absorbed into the micropipette 4 by capillarity or the negative pressure given by the system described above. Next, this micropipette 4 is so arranged as to supply the liquid to the desired position on the surface. The positive pressure is applied on the inside of the micropipette 4 in order to supply the liquid. The liquid drops below the micron size are forcibly discharged from the micropipette 4 by the positive pressure. Various kinds of the members constituting microminiature electromechanical devices and microminiature mechanical devices are fixed to suitable points by using the liquid drops of the adhesives below the micron size formed by using this method.

Abstract: PROBLEM TO BE SOLVED: To provide a method for forming a liquid drop having a micrometer size or less. SOLUTION: A micro-pipet having an inner diameter not more than the size of a liquid drop to be formed is connected to a system for applying positive pressure and, according to circumstances, negative pressure to the interior of the micro-pipet. The leading end of the micro-pipe is brought into contact with a liquid. This liquid is sucked into the micro-pipe by capillary action or under the negative pressure applied by the system. Next, the micro-pipet is arranged so as to supply the liquid to the desired position on a surface. Positive pressure is applied to the interior of the micro-pipet in order to supply the liquid. The liquid drop with a micrometer size or less is forcibly discharged from the micro-pipet by the positive pressure. The liquid drop of an adhesive with a micrometer size or less formed by this method is used to fix various members constituting an ultra miniature electromechanical device or ultra miniature mechanical device.

Abstract: PROBLEM TO BE SOLVED: To enable movement in three dimensional directions on an accurate submicron scale by providing a z-axis direction driving means out of the plane formed by x-axis and y-axis direction driving means. SOLUTION: In an xy stage 4, x-axis and y-axis direction driving means 20 and 40 moves a sample stage 12 in an x-y plane via links 14 and 16. In an xyz stage 2, a z-axis direction driving means 48 added to the xy stage 4 suspends a flat electrode 50 via a supporting means 54 and accesses the sample stage 12 vertically from the through opening 52 of the flat electrode 50. When a voltage is placed to the flat electrode 50 via a wire 76 to an electrode 70, an electrostatic force is generated between the sample stage 12 and the flat electrode 50, and the sample stage 12 is moved from the x-y plane in the direction of the flat electrode 50 as if springing out. Its location is detected by an accurate capacitance bridge to control the movement in a z-direction approximately within 20 nm. This enables movement in three dimensional directions in a submicron scale.

Abstract: PROBLEM TO BE SOLVED: To provide a micron sized self assembly type mechanical component. SOLUTION: A mechanical component is configured so that hinge-equipped plates 2 are installed on a base board 6. A beam 8 having a first free end moves upward in such a way as drawing an arc, and at the free end, a first fit-in member 18 is installed. Each plate 2 has a second fit-in member 22, and before assembly, the first fit-in member 18 is positioned under the second fit-in member 22. When a drive force is given by an actuator, the free end of the beam 8 is lifted, and the first and second inclining edges slide with each other, and the hinge-equipped plates 2 rotate upward round the hinges as going apart from the base board 6. Thus, the plates 2 can rotate more than 90 deg. from a supporting board.

Abstract: PROBLEM TO BE SOLVED: To prevent a light signal from entering a destination fiber by going over a gap by mechanically connecting an actuator and a reflector, and changing a light-actuated photon switch state by moving the reflector by actuation of the actuator. SOLUTION: When a photogenerator 104 is irradiated by a light beam 112 through an optical fiber 110, the generator 104 generates voltage, and the voltage is transmitted to an actuator 126 of a microscopic electronic machine system MEMS structure 124 through electric conductors 106 and 108. When the voltage is transmitted, a reflector 130 capable of changing a light signal characteristic by reflection, diffraction, absorption and the others, moves to a passage of a signal 134 from a signal source fiber 132a by a connecting mechanism 128. Therefore, the light signal 134 can be prevented from reaching a destination fiber 132E by going over a gap 136. Here, the dimension of the gap 136 can be comparatively reduced to about 20 μm without a lens, and becomes fairly large with a lens.

Abstract: PROBLEM TO BE SOLVED: To provide adaptive optics in the type of a micromachined mirror to eliminate the optical/mechanical independence of a uniform reflection layer and to eliminate the many actuators of the conventional mirror arrays. SOLUTION: This article for directing a light signal between optical waveguides is disclosed. The article includes plural mirror elements which are mechanically and electrically interconnected and form reflection surfaces. The reflection surfaces can be deformed by impression of voltage. The light signal sent from the source waveguide can be directed to the different destination waveguides when the reflection surfaces are deformed. The plural mirror elements are actuated by the single actuator.

Abstract: PROBLEM TO BE SOLVED: To obtain an optical bypass-exchange switch which switches a bypass state and exchange state suitable for a wide range of applications by providing the optical switch with a telecentric imagery device which effectively carries signals from input to output and an optical director which may be so operated as to change the path of the optical signals. SOLUTION: The optical bypass-exchange switch 102 has the telecentric imagery device 104 and the optical director and is operated by the two states enabled by the optical director. The telecentric imagery device 104 receives the first optical signal 192 and is made to form the image in at least one of the first output 90b and the second output 90d. The optical director changes the operation of the optical switch between the exchange state and the bypass state. The first optical signal 92 is imaged in the first output 90b in the exchange state and the first optical signal 91 is imaged to the second output 90d in the bypass state. Then, the switching function is executed when either of the two states, exchange and bypass, is enabled.

Abstract: PROBLEM TO BE SOLVED: To obtain a switch which is low in cost and is high in a switching rate by providing this switch with a link mechanism capable of moving an optical device between a first position deviating from an optical path and a second position within the optical path by the reciprocating motion of a moving plate. SOLUTION: The optical switch 2a has a hinged plate actuator 4a, the optical device 8 and the link mechanism 6a. The link mechanism 6a mechanically links or interconnects the hinged plate actuator 4a to the optical device 8. The link mechanism 6a exists along an axis 1-1. This axis 1-1 passes by a gap 10 between waveguides 12 and 14. The link mechanism 6a and the optical device 8 exist relative to the waveguides 12 and 14 in such a manner that the both are movable between the first position where the optical device 8 exists in the path of the light signal moving between the fibers and the second position where the device exists off the path.
