Abstract: The present invention provides a micro-electro-mechanical system (MEMS) optical device (100). The micro-electro-mechanical system (MEMS) optical device (100) includes a mirror (110) having a substrate (140) with an implanted light reflective optical layer (130) thereover, and a mounting substrate (120) on which the mirror (110) is movably mounted. The inclusion of the dopant (150) within the light reflective optical layer (130) increases the tensile stress of the device (100) and tends to correct the concave curvature of the mirror structure toward a desirably flat configuration.

Abstract: In accordance with the invention, an optical cross-connect switch includes an optical router for distributing multi-wavelength optical input signals, an optical combiner for supplying multi-wavelength signals at the output ports of the switch, an d optical fibers for interconnecting the optical router and optical combiner. Selected interconnecting optical fibers include controllable wavelength-selective elements, such as magnetically controllable fiber gratings, which are capable of transmitting or reflecting individual channels within the multi-wavelength optical signals so that a selected channel of a particular wavelength can be routed from any of the input ports to any of the output ports of the switch.

Abstract: A method for making a chirped grating device capable of a broad bandwid th for optical communication systems is disclosed. An intrinsically-chirped optical grating is externally strained to alter the range of chirping. The external strain may be induced by a gradient-generating body bonded onto the length of the fiber grating that may be latchably strained so that the grating characteristics may be changed or tuned while avoiding use of a continuous power supply. Various optical networking applications using such dispersion compensating devices are also disclosed.

Abstract: A tunable optical grating device (10) that can be digitally and latchably tuned comprises a length of waveguide (11) including a grating region (12), and a movable body (14) and fixed substrate (16) attached to the waveguide proximal the grating region. The body is movable from a first position to at least a second position, and in some embodiments to a plurality of positions, along the length of the waveguide to apply a mechanical strain to the grating to shift the wavelength response of the device. The movable body is latchable between the various positions along the length of the waveguide to define a latchably tunable device so that a continuous supply of power is not needed to tune the device. The digitally and latchably tunable optical grating device is useful in WDM communication systems, particularly for adding or dropping channels and for dynamically gain-equalizing optical amplifiers.

Abstract: A tunable chromatic dispersion compensator for optical communication systems is disclosed. An optical grating, such as a fiber Bragg grating, non-chirped, linearly chirped or non-linearly chirped, is coated on its outer surface with a coating have a variable diameter and strained is applied to the fiber. The fiber may be latchably strained so that the grating characteristics may be changed or tuned while avoiding use of a continuous power supply. Various optical networking applications using such dispersion compensating devices are also disclosed.

Abstract: The invention provides a device with an improved tunable laser structure, the structure useful with surface emitting lasers and capable of exhibiting desirable latchability. The tunable laser of the invention contains a laser structure having a lower reflector, an active laser region, and an upper reflector. The upper reflector contains a non-moveable reflector portion located adjacent the active laser region and a moveable reflector portion located a spaced distance from the non-moveable reflector portion. A magnetic material is located either on a surface of the moveable reflector portion or on a surface in contact with the moveable reflector portion, and a programmable magnet is located near the magnetic material, the magnet capable of inducing controlled movement of the magnetic material. This movement in turn induces movement of the moveable reflector portion such that the spaced distance between the moveable reflector portion and the non-moveable reflector portion is capable of being adjusted. By adjusting this spaced distance (i.e., the air gap between the moveable and non-moveable reflector portions), the phase of reflection and thus the laser output wavelength is controlled.
