The effects of base width variation on resonance behavior of Double-Hetero structure long wavelength transistor laser

Base width variation effects on resonance frequency and resonance peak of Double-Hetero structure Long Wavelength Transistor Laser (DH-LWTL) is investigated. Resonance behavior has significant effects on optoelectronic performance of LWTL that calculated through its frequency response. In our structure, resonance peak maximized to 16.23 dB in 135 nm base width. Also, in 305 nm base width, resonance frequency saturated around 24 GHz.
