Abstract

DBR lasers can exhibit significant frequency-errors when operated in which a random frequency-hopping schedule. We introduce a simple thermal model which anticipates the frequency errors a change in schedule induces. Experiments were performed which confirm the validity of the model. A compensation scheme is developed which reduces the worst case frequency error range from 32.1 to 7.9 GHz.
