PROBLEM TO BE SOLVED: To provide a blue laser with reduced power output variations due to transient heating. SOLUTION: A III-V nitride blue laser diode in a short periodic table has an amplifier region 116 and a modulator region 118. The amplifier region 116 has a constant current to keep the region near a lasing threshold. The modulator region 118 has a small varying forward current or reverse bias voltage which controls the light output of the laser. Since this two-section blue laser diode requires much lower power consumption than directly modulated lasers, transient heating and "drooping" of the light output are reduced.
