摘要： A method of selectively tuning the bandedge of a semiconductor heterostructure includes forming a disordered region (11) which is spatially separated from a quantum well active region (12), and subsequently annealing the heterostructure so that vacancies/defects in the disordered region (11) diffuse into the quantum well region (12) and enhance interdiffusion at the well-barrier heterojunctions. The tuning is spatially selective when the heterostructure is masked so that exposed portions correspond to regions where bandgap tuning is desirable. The heterostructures of interest are III-V material systems, such as

AlGaAs/GaAs

, where the active region includes structures such as a single quantum well, a multiple quantum well, or a superlattice.

摘要： An optical multiplexer/demultiplexer (11) provides for arbitrarily closely spaced wavelength channels (18, 19, 21, 22), the spacing and locations thereof being determined by the thickness of birefringent crystals such as, for example, quartz. Such a device can also be used for duplexing bidirectional signals. Methods for mechanically tuning the devices to given laser wavelengths are described, as well as simplified constructions which can be used with polarized light sources such as lasers.

摘要： Polarization-insensitive optical switch and dual channel carrier multiplexer includes a polarization beam splitter (13) for receiving an input collimated beam (12) which has arbitrarily polarized components, splitting the beam (12) into the two components (P, S). One of the components (P) is rotated by a 1/2 wave plate (14) so as to yield a polarized beam (S) which is polarized in the same direction as the other beam (S). The two polarized beams (S, S) are then applied to a polarization sensitive interferometric multimode fiber optic switch and modulator (11). The output of the interferometric multimode fiber optic switch and modulator (11) contains two beams (S, S), both polarized in the same direction. One of the beams (S) is rotated ninety degrees by a 1/2 wave plate (19), and the two mutually perpendicularly polarized beams (P, S) are then recombined by a polarization beam splitter (18) operated in reverse to yield an output beam (21) containing mutually perpendicular components.

摘要： interferometric multimode fiber optic switches and modulators include combinations of various components. Two electro-optical crystals (27, 37) have a dielectric beam splitting coating (48) affixed to portions thereof. The coated portions of the two crystals are juxtaposed. Means (17, 18, 19, 20, 22, 51, 52, 53, 54) are provided for varying the indices of refraction of the two crystals (27, 37) with respect to each other. Light entering into the first crystal (27) and travelling within the two crystals (27, 37) can be switched to selectively exit from one crystal (27) or from the other (37) by varying the index of refraction of one of the crystals (27, 37) with respect to that of the other. By interferometric principle of operation, the phase relation of light is transformed into spacial direction. The crystals (27, 37) can be selected from the group consisting of lithium niobate, lithium tantalate, and barium strontium niobate. The dielectric beam splitting coating (48) can be formed of multiple layers of material such as zirconium oxide and silicon dioxide. The indices of refraction of the crystals (27, 37) are varied by applying electric fields of one polarity at opposite surfaces thereof. Light enters the various crystals (27, 37), and is reflected, and is transmitted at various surfaces (31, 34, 42, 46) thereof so that, upon entering a particular area, within the crystals (27, 37), reinforcement or interference of light can occur.

摘要： A four channel optical multiplexer can be simplified when the polarisation state of the input signals is known. Such an improved four channel optical multiplexer (50) consists of three polarisation beamsplitters (52, 53, 54), a reflecting surface and a simple birefringent crystal (51) such as, for example, quartz. The spacing and location of the wavelength channels (λ1, λ2, λ3, λ4) is determined by the thickness of the single birefringent crystal (51).
