| 英文摘要 | PURPOSE:To suppress the effect of reflected light to a semiconductor laser with the minimum offset quantity, in the semiconductor laser having a double heterostruction, by offsetting the light axis of one lens to a specified direction. CONSTITUTION:An outgoing beam from the semiconductor laser 1 having the double heterostruction 21 is coupled with optical fiber 5 through lens 2, a laser package window 3, and a lens 4. The light axis AA' of the lens 2 is perpendicular to the plane of the double heterostruction 21 of the laser 1 and offset by DELTAx with respect to the light axis of the outgoing beam within a plane (x-z plane) including the light axis OO' of the outgoing beam. Since the lens 2 is offset by DELTAx with respect to the light axis of the laser beam, the effect of the reflected light to the semiconductor laser can be suppressed with the minimum offset quantity. |
