Abstract

In one embodiment, a transmitter can bias a vertical-cavity surface-emitting laser (VCSEL) coupled to an optical medium. The biasing of the VCSEL determines at least in part an optical power output by the VCSEL to the optical medium. The transmitter can also modulate the VCSEL with data to transmit the data optically through the optical medium to a receiver; receive from the receiver through a feedback channel an error vector representing a degradation in performance of the VCSEL sensed by the receiver or an instruction vector comprising one or more coefficients for use in biasing the VCSEL; and adjust the biasing of the VCSEL based on the error vector or the instruction vector to regulate the optical power output by the VCSEL to the optical medium.
