| 英文摘要 | PURPOSE:To enable a semiconductor laser to be controlled in oscillation wavelength in a wide range without providing a grating externally by a method wherein distribution reflectors different from each other in Bragg wavelength are selected. CONSTITUTION:When no current is made to flow through an optical switch 2, light emitted from an active layer 4 is made to advance from a waveguide 16 on the active layer 14 side to a distribution reflector 1a passing through a waveguide 17a on a reflector side, and when a current is made to flow through the optical switch 2, light is totally reflected by the optical switch 2, the optical path is switched to a waveguide 17b on a reflector side, and the light is guided to a distribution reflector 1b. By switching an optical path, oscillation laser light can be roughly set in wavelength. A fine adjustment of laser light in wavelength can be made through such a way that a current flowing through an oscillated distribution reflector and another current flowing through a phase control region 3 are set different from each other in intensity. |
