Abstract :
We report on the signal monitoring characteristics in a reflective semiconductor optical amplifier (RSOA) transistor outline can with a monitor-photodiode, thermoelectric cooler, and thermistor. Because of spatial hole-burning in the RSOA cavity, a front-side signal-monitoring module exhibits wider windows and better linearity in monitor current to signal power ratio (MCSPR) than a rear-side signal-monitoring module for current variations. In C-band, the average of the MCSPR is about 0.150 A/W and the MCSPR variation on wavelength is about ±0.038 A/W.
