Semiconductor laser with external cavity having non-straight waveguide |
| abstract |
The present invention relates to a semiconductor laser with an external cavity having a non-straight waveguide, in which a semiconductor laser diode used as an optical gain medium has a nonreflective coated side, light emitted from the laser diode chip is collected to a waveguide type of waveguide-selective filter and light having a wavelength selected by a grating on the waveguide is fed back to the laser diode chip, and the wavelength of emitted light is changed by electrically or thermally changing the properties of the waveguide. n A laser with an external cavity having a non-straight waveguide according to the present invention is formed in a TO-can type package, in which a semiconductor laser diode chip and a waveguide with a grating are disposed, the wavelength of light from the semiconductor laser is determined by the grating of the waveguide, and an exit surface and an incident surface of the waveguide are formed in the same direction |
