<p>A III-V nitride blue laser diode (100) has an amplifier (116) region and a modulator (118) region. The amplifier region (116) has a constant current to keep the region near the lasing threshold. The modulator region has a small varying forward current or reverse bias voltage which controls the light output of the laser (100). This two section blue laser diode requires much lower power consumption than directly modulated lasers which reduces transient heating and "drooping" of the light output. <IMAGE></p> |
