APC receptacle type cooled RSOA-TOSA with low return loss and high coupling efficiency was successfully developed for field-deployed WDM-PON application.
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...
We reports power monitoring characteristics in RSOA TO-module with m-PD, TEC and thermistor. By monitoring output power at the front of RSOA, monitor current linearity can be improved and monitoring window becomes wider.
