Abstract: Systems and techniques for laser transmitter characterization for accurate laser aging are described herein. A set of bias current-temperature pairs is collected for a laser diode. A bias current-temperature curve is calculated for the laser diode using the set of bias current-temperature pairs. A timestamp is assigned to the bias current-temperature curve. The bias current-temperature curve and the timestamp are stored in a non-volatile memory device communicatively coupled to a laser device that includes the laser diode. The bias current-temperature curve and the timestamp are transmitted to a cloud-based storage facility.
