| 英文摘要 | PURPOSE:To realize higher output and higher efficiency of a semiconductor laser with suppressed leak current by a method wherein a low conductivity ratio semiconductor layer is formed on a current strangulation layer. CONSTITUTION:A V-shaped groove is formed with etching liquid consisting of a solution of hydrochloric acid and phosphoric acid. The width of the groove is approx. 5mum an the depth is approx. 2mum. After that, a p-In clad layer 50, an undoped InGaAs active layer 60, an n-InP layer 70, and an n-InGaAa contact layer 80 are grown. This semiconductor laser wafer is cleaved to a length for a 800mum resonator to obtain a semiconductor laser. |
