Abstract: | Simulation results of frequency conversion up to the terahertz region in semiconductor laser devices, both in bulk and quantum-well structures, are presented with a comparison of traveling wave amplifiers and Fabry—Perot oscillators. In both devices conversion gains greater than 0 dB can be achieved with a proper parameter choice. Interesting features of the conversion gain spectra for the oscillator-converter are pointed out with a discussion of the performances. |
