Applications of semiconductor optical amplifiers
2012 17th Opto-Electronics and Communications Conference, 2012All-optical processing of phase encoded signals with nonlinear semiconductor optical amplifiers offers potential advantages. As examples, we demonstrate QPSK to 8PSK conversion and decomposition of QPSK to two BPSK outputs at new wavelengths.

Quantum-Dot Semiconductor Optical Amplifiers
Proceedings of the IEEE, 2007This paper reviews the recent progress of quantum-dot semiconductor optical amplifiers developed as ultrawideband polarization-insensitive high-power amplifiers, high-speed signal regenerators, and wideband wavelength converters. A semiconductor optical amplifier having a gain of > 25 dB, noise figure of 20 dBm, over the record widest bandwidth of 90

Vertical-cavity semiconductor optical amplifiers
LEOS 2000. 2000 IEEE Annual Meeting Conference Proceedings. 13th Annual Meeting. IEEE Lasers and Electro-Optics Society 2000 Annual Meeting (Cat. No.00CH37080), 2002The structure of our vertical cavity semiconductor optical amplifier (VCSOA) is shown. The device was optically pumped through the substrate and bottom mirror using a 980 nm pump laser diode, and was operated in reflection mode. Two high reflectivity GaAs-AlGaAs distributed Bragg reflector (DBR) mirrors were wafer bonded to an InP-InGaAsP multiple ...
