ETN aims to acquire the recent and outstanding researches for the benefit of the human being.
We present numerical analysis of a slow-light vertical-cavity surface-emitting laser (VCSEL) amplifier basing on a travelling wave model. The model takes into account two oscillating modes; the vertical lasing mode and a slow light mode. We describe the amplification of the slow light mode through the amplifier when it is biased above the threshold level of the vertical lasing mode. The output power is investigated at different bias currents and lengths of the amplifier. The numerical results ascertain the possibility to obtain high gain more than 22 dB for amplifier length of 1 mm.
Keywords: Bragg reflectors, high power lasers, slow light, VCSEL.
