Semiconductor laser device and method for suppressing fabry perot oscillations |
摘要 |
A semiconductor laser device includes an active layer configured to radiate light, a light reflecting facet positioned on a first side of the active layer, and a light emitting facet positioned on a second side of the active layer thereby forming a resonator between the light reflecting facet and the light emitting facet. A diffraction grating is positioned within the resonator along a portion of the length of the active layer and the laser device is configured to operate as a multiple mode oscillation device. A window structure is provided between an end of the active layer and one of the light reflecting and light emitting facets, and the window structure is configured to reduce a reflectivity of the one of the light reflecting and light emitting facets.
