摘要： Methods and processes are disclosed for calibrating optoelectronic devices, such as optoelectronic transceivers and optoelectronic receivers, based upon an avalanche photodiode breakdown voltage. In general, the method involves adjusting a reverse-bias voltage of the avalanche photodiode until avalanche breakdown of the avalanche photodiode occurs. An optimized APD reverse-bias voltage is then determined by reducing the reverse-bias voltage at which avalanche breakdown occurs by a predetermined offset voltage. This process is performed at a variety of different temperatures. Information concerning each temperature and the corresponding optimized APD reverse-bias voltage is stored in a memory of the optoelectronic device.
