Abstract: In accordance with the invention, a tunable, reconfigurable optical add-drop filter comprises a pair of optical waveguides optically coupled by a microring or microdisk resonator wherein the coupling distance between the resonator and at least one of the waveguides is micromechanically controllable. With this arrangement, the degree of coupling can be tuned after fabrication to provide high level extinction of dropped wavelengths and the filter can be dynamically reconfigured. Advantageously, laser radiation is provided to tune the resonant wavelength.

Abstract: An optical demultiplexing apparatus is capable of spatially separating a multiplexed optical signal into two or more optical wavelength signals thereof. An input multiplexed optical signal present on a first plane is imaged through a color-selective grating plane to a second plane. The color-selective grating has a nonlinear change of diffraction characteristics as a function of incident wavelength to provide substantial spatial separation in the second plane between bands of wavelengths proximate to the two or more optical wavelength signals. In another embodiment, the apparatus uses a polarization-selective grating to spatially separate a polarization-multiplexed optical signal into two substantial spatially separated optical polarization signals. In other embodiments, the optical apparatus may be used as an optical signal multiplexer, splitter, or combiner.

Abstract: An integrated semiconductor device is formed from two fabricated semiconductor devices each having a substrate by placing an etch-resist on the substrate of the one semiconductor device, by bonding the conductors of one of the fabricated semiconductor devices to the conductors of the other fabricated semiconductor device, flowing an uncured cement (e.g. epoxy) between the etch-resist and the other substrate, allowing the cement to solidify, and removing the substrate from the one of the semiconductor devices. More specifically, a hybrid semiconductor device is formed from a GaAs/AlGaAs multiple quantum well modulator having a substrate and an IC chip having a substrate by placing an etch resist on the modulator substrate, bonding the conductors of the modulator to the conductors of the chip, wicking an uncured epoxy between the modulators and the chip, allowing the epoxy to cure, and removing the substrate from the modulator.

Abstract: An optical assembly for detecting an optical signal from a signal source in systems where the intensity of the optical signal may surpass the operational range of the optical detector being used. The optical assembly includes an optical detector for converting the optical input signal into a corresponding electrical output signal. The optical detector has a set operational range of input signal intensities. An attenuator is disposed between the optical detector and the signal source. The attenuator is capable of reducing the signal intensity of the optical signal if required so that the optical signal falls within the operational range of the optical detector. A controller is electronically coupled to both the optical detector and the attenuator. The controller controls the attenuator as a function of the output signal of the optical detector, wherein the attenuator attenuates the optical signal to fall within the operational range of the optical detector.

Abstract: In an optical transmitter, an input optical fiber delivers an optical signal to a fiber coupling modulator whose reflective surface is transformable in response to the data to be transmitted. In a first state of the modulator corresponding to a first data value, the reflective surface is flat and smooth. The optical signal, which may be a continuous-wave light, is reflected from the surface and efficiently coupled to an output fiber. In a second state of the modulator corresponding to a second data value, the reflective surface is controllably deformed to cause an aberration in reflecting the optical signal. As a result, a much reduced amount of light energy is coupled to the output fiber.
