Abstract
A device includes an array of optical transmitters having first and second temperature sensors each disposed at or near a first and second end of the array of the transmitters. The device includes a controller in communication with the temperature sensors and the transmitters. The controller receives temperature measurements from the temperatures sensors and determines a temperature difference between a first temperature measurement of the first temperature sensor and a second temperature measurement of the second temperature sensor. The controller determines a compensation for each transmitter within the transmitter array based on the temperature difference and a transmitter position within the array of transmitters. The compensation causes the corresponding transmitter to transmit at a wavelength associated with that transmitter. The controller executes the compensations for the transmitters.
