The use of a directional terminal antenna on a wireless link can enhance received power by as much as the antenna gain. In local scattering, however, the enhancement will be smaller.
The gain saturation of optical amplifiers due to changes in wavelength-division-multiplexed channel loading is characterized using a technique that determines the saturation effect on each channel.
We present a device which produces changes in the slope of its transmitted spectra via an applied bias, a Spectrally Linear Optical Power Equalizer, or SLOPE device.
We report on the spatial uniformity of the gain M of InP/InGaAsP/InGaAs avalanche photodiodes with separate absorption, grading, and multiplication regions (SAGM-APDs).
This work enables one to obtain the potential gain (G(T)) characteristics with the associated source (Z(S)) and load (Z(L)) termination functions, depending upon the input mismatching (V-i), noise
Optical notch and long-period grating (LPG) gain-equalizing filters are modeled and studied, and their performances are compared and contrasted for the case of optical waveguide amplifiers for inte
Modes in cylindrical structures with refractive index boundaries are well known.
We demonstrated gain-switching of several 5 and 8-μm quantum cascade lasers.
Quantum well structures containing single isolated structures and superlattices of GaInAs/InP and GaInAsP/InP and GaInAsP/InP have been grown by gas source MBE to establish the current limits of di
Proposes two new structures, the GaInAs-GaInNAs intermediate layer (IML) and the GaInN/sub x/As graded wells, which show better optical properties than the commonly used GaInNAs-GaAs rectangular qu
