Bidirectional Semiconductor Laser

Science, 1999
A semiconductor laser capable of operating under both positive and negative bias voltage is reported. Its active region behaves functionally as two different laser materials, emitting different wavelengths, depending on the design, when biased with opposite polarities. This concept was used for the generation of two wavelengths (6.3 and 6.5 micrometers)

Semiconductor Interferometric Laser

Topical Meeting on Integrated and Guided-Wave Optics, 1982
Wavelength control of semiconductor lasers is important in optical communication, where mode stability, tunability, and FM modulation are vital to high quality transmission. Numerous work had been done in optimizing stripe geometry lasers to achieve mode stability.

Semiconductor Raman laser

Journal of Applied Physics, 1980
The semiconductor Raman laser has been realized by using a GaP crystal. Pumping is made by a Q-switched YAG laser operating at 1.064 μm. The round-trip loss in the Fabry-Perot resonator is 2% or less. The Raman scattering from LO phonons stimulates in the 〈100〉 direction, while the forward and backward Raman scattering from TO phonons stimulate in the 〈
