摘要： A GaAs FET structure with a high electric field region, or active region, contacted by source, gate and drain electrodes is provided which can be used for high speed optical detection or for microwave oscillator optical injection locking. The device provides for efficient coupling of optical radiation into the active region through an opening in a semi-insulating substrate used to support the device. A buffer layer between the active region and the substrate prevents leakage current to the substrate, permits a larger illumination window for improved optical coupling and provides mechanical support for the FET detector. GaAs photodetectors are also provided by eliminating the gate electrode.

摘要： A superluminescent light-emitting diode in which the spectral width of the output increases with increasing optical output power, thereby allowing the generation of high optical output powers with a broad frequency spectrum that is desirable for some applications of the superluminescent diodes. This desirable characteristic is obtained by structuring the diode to produce a non-uniform gain profile across its active layer. Alternative approaches for achieving the non-uniform gain profile include varying the thickness of the active layer, and varying the current density by employing an asymmetrical channel configuration or an asymmetrical electrical contact strip.

摘要： A semiconductor laser diode structure operable at high power and brightness levels and having a relatively low threshold current, high efficiency, good mode stability, and reduced temperature sensitivity. The disclosed embodiments have twin parallel channels formed in a p type substrate, and employ an n type blocking layer to confine current to a region between and including the channels. The structure includes first and second inactive cladding layers, and an active layer forming a diode junction. The first or lower inactive layer is thinner in the region between the channels, and this results in a higher forward-bias voltage at the center of the active layer, thereby focusing the current near the central position. This current focusing mechanism, which is enhanced by the optional use of a curved active layer, results in the improved characteristics of the structure. By selecting the effective width of a contact stripe overlying the second or upper inactive layer, single or multiple optical gain filaments may be produced.
