Abstract
A temperature insensitive vertical cavity laser includes an active region, having a plurality of quantum wells, formed between first and second mirrors. The gain of each of said quantum wells or groups of quantum wells operate quasi-independently at different temperatures such that stimulated emission is dominated by a different quantum well or group of quantum wells at different temperatures.
