Abstract: This invention is predicated on applicants' discovery that a highly oriented nanoconductor structure alone does not guarantee efficient field emission. To the contrary, the conventional densely populated, highly oriented structures actually yield relatively poor field emission characteristics. Applicants have determined that the individual nanoconductors in conventional assemblies are so closely spaced that they shield each other from effective field concentration at the ends, thus diminishing the driving force for efficient electron emission. In accordance with the invention, an improved field emitting nanoconductors assembly (a “low density nanoconductor assembly”) comprises an array of nanoconductors which are highly aligned but spaced from each other no closer than 10% of the height of the nanoconductors. In this way, the field strength at the ends will be at least 50% of the maximal field concentration possible. Several ways of making the optimally low density assemblies are described along with several devices employing the assemblies.

Abstract translation: 本发明基于申请人的发现，即单独的高度取向的纳米结构结构不能保证有效的场发射。 相反，传统的人口稠密，高度取向的结构实际上产生相对较差的场致发射特性。 申请人已经确定，常规组件中的单个纳米电感器如此紧密地间隔开，使得它们彼此屏蔽在端部处的有效场浓度，从而减少了有效电子发射的驱动力。根据本发明，改进的场发射纳米结构器件组件 “低密度纳米导体组件”）包括高度对准但彼此间隔不超过纳米电感器高度的10％的纳米电感器阵列。 以这种方式，末端的场强将是可能的最大场浓度的至少50％。 使用几种使用组件的装置来描述制造最佳低密度组件的几种方式。

Abstract: A variable attenuator device is disclosed that may be magnetically and latchably controlled such that it does not require a continuous power supply to maintain a particular loss level. The variable attenuator comprises two optical components disposed in spaced apart relation to define a gap between them and a magnetic shutter positioned within the gap. The shutter is movable, due to its magnetic properties, from a first position to at least a second position, where the second position may be within, partially within, or outside of the gap. A mechanism is provided for magnetizing or actuating the shutter to cause it to move from the first position to the at least second position. When the shutter is in the first position, it causes a certain amount of attenuation in the signal being transmitted between the two optical components, and when it moves to the at least second position, a different amount of attenuation is caused, such that movement of the shutter causes a variation in the attenuation. With this attenuator, the variation in attenuation may be achieved via coupling loss while the optical components (e.g., mating fibers), are maintained in a fixed position, thereby avoiding difficulties associated with fiber movement.

Abstract: A method for making a chirped grating device capable of a broad bandwith 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: 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.

Abstract: In accordance with the invention, a passively temperature-compensated tunable optical grating device comprises a grating, which is fixed at both ends to a support frame, and is mechanically or magnetically flexed so that a tensile strain induced in the grating reconfigures the resonant wavelength of the grating. Preferred embodiments include at least one waveguide grating, a flexing mechanism capable of inducing a latchable change in grating periodicity and at least one negative thermal expansion component which, upon heating, reduces the strain in the grating so that the temperature-induced wavelength shift is substantially cancelled out. The device can reduce the temperature-dependent wavelength change to less than 0.5 nm/100 deg. C, and preferably less than 0.05 nm/100 deg. C. In a preferred embodiment, the packaging assembly also includes a fine-wavelength adjusting mechanism for post-assembly corrective tuning. The device is especially useful in WDM communication systems, particularly for adding or dropping channels, for dynamically gain-equalizing optical amplifiers, for tunable lasers, and for dispersion compensation.
