Performance characteristics of high speed laser diodes under thermal-irradiated operating conditions
In the present paper, under thermal-irradiated operating conditions, the performance characteristics of high speed laser diodes (based on Vertical Cavity Surface Emitting Laser (VCSELs)) are deeply and parametrically investigated. The processed characteristics are: the harmonic response transfer function, the resonance frequency, 3-dB bandwidth and the rise time. These diodes affect the transmitted bit-rate...
