DESCRIPTION

The SML2108 is an adaptive power controller for laser diodes. It is the industrys first integrated device that can directly monitor and measure a laser diodes temperature, and provide a variable modulation current. The SML2108s integrated active feedback loop is used to calibrate and control the mean and modulation power of high speed, high power laser diodes.
