Abstract

A semiconductor laser comprising an optical generation section and a heat balancing region, wherein each region of the optical generation section is paired with associated means in a corresponding region of the heat balancing section and is in thermal communication with such associated means. In operation the total input electrical power applied to said region and its associated means is constant and independent of the electrical power applied to the other regions and their respective associated means. Preferably, each region and its associated means have substantially identical structures.
