摘要： Crosstalk for a directional coupler switch (10) employing a reversed Δβ electrode structure is reduced to a minimum by properly placing electrode sections (13, 14, 15, 16) over the waveguides (20, 21) to compensate interwaveguide coupling preceding an electrode section with interwaveguide coupling following the electrode section.

摘要： An interferometric modulator comprising a substrate of titanium-doped lithium niobate (Ti:LiNbO₃) having top and bottom surfaces and a waveguide formed in the top surface is disclosed. A conductive layer is formed on the bottom surface of the substrate and electrically coupled to a top-surface ground plane or simply to ground potential. The bottom surface conductive layer functions to thermally stabilize the modulator during operation.

摘要： This invention relates to a device for generating solitons by amplitude modulating an optical signal with separate in-phase electrical signals of different harmonically related frequencies. Specifically, an amplitude modulator such as a Y junction Mach-Zehnder interferometer (23, 25, 26, 28) has multiple sets of distributed electrodes (50, 52...64). The interferometer has a set of electrodes for each electrical signal of a specific frequency, thus, if three separate signals of harmonically related frequencies are used to amplitude modulate an optical signal, then the interferometer has three sets of electrodes located between the Y junctions (30) of the Mach-Zehnder interferometer. The structure of a separate set of electrodes for each of the signals results in a soliton generator which avoids the prior art problem of signal loss caused by combiningg many high frequency signals into a composite signal and the resulting need for a relatively expensive amplifier capable of uniformly amplifying the multi-octave composite signal.

摘要： An optical intersection with reduced transmission loss is described. An embodiment of the inventive interconnection comprises two intersecting waveguides. According to the teachings of the invention, deleterious asymmetric field distortions in the waveguides, associated with the presence of the adjacent waveguides, are reduced by, for example, changing the width of the intersection region, and the widths of the waveguides as they approach the intersection region.

摘要： An optical amplifier and a photodetector are positioned side-by-side on the same semiconductor chip. A portion of the electromagnetic energy carried in the evanescent tail of the optical mode of the amplifier is detected by the photodetector for monitoring the average output power of the optical amplifier. Current confinement and lateral index guiding can be provided by Fe or Ti doped semi-insulating layers of InP (20). The side-by-side arrangement enables the detector to monitor the output power of the optical amplifier without degrading the output power of the optical amplifier.

摘要： The device here disclosed comprises an optical amplifier (12) coupled to direct optical energy into a passive wavegulde (16,14,21) for transmission through the waveguide to its other end. A photodetector (8) positioned relative to the passive waveguide, detects the presence of optical energy in the passive waveguide. The photodetector in the structure illustrated is positioned downstream from the optical amplifier and spatially positioned with respect to the optical amplifier to receive optical energy only from the waveguide. The photodetector does not receive optical energy directly from the optical amplifier. A small fraction of the optical energy carried by the passive waveguide is received and detected by the photodetector.
