| 英文摘要 | PURPOSE:To realize a laser device for laser printer which has good droop characteristics and is free from print irregularities when a printer is used, by setting the reflectance of a front edge side of a semiconductor device for a laser printer at a specified value. CONSTITUTION:In a laser chip 1 for a laser printer which is designed to project laser beam 8 for monitor and main laser beam 7, a reflection film 2 is formed at the edge of a side to project the main laser beam 7. The reflectance of the laser beam by the reflection film 2 is set in a range from 45% to 65%. The external differential quantum efficiency is thereby reduced and the difference between operational current and threshold current increases, thus reducing the influence of threshold current variation to light output. Droop is consequently reduced. |
