Abstract :
In the present paper, under thermal operating conditions, the performance characteristics of high speed laser diode (based on vertical cavity surface emitting laser (VCSEL)) is deeply and parametrically investigated. The processed characteristics are : the harmonic response transfer function, both the resonance frequency and 3-dB band-width, and the rise time. These diodes affect the transmitted bit-rate in high-speed advanced optical communication systems. The effects of both ambient temperature (and consequently the inner temperature) and the injected current (power) are deeply investigated. The pulse rise time, and the resonance frequency as well as the 3-dB bandwidth are the major criterions of the device speed. It is found that the device undergoes good performance: higher resonance frequency, higher bandwidth, and smaller rise time as the proposed figure of merit increases
