Semiconductor light emitting module |
摘要 |
A fiber grating laser module comprises a semiconductor optical amplifier and a grating fiber in which a Bragg grating is formed in the core. The semiconductor optical amplifier provides a wave guide in which the light is generated and amplified by the carrier injection, the light emitting facet and the light reflecting facet. The Bragg grating in the grating fiber and the light reflecting facet of the semiconductor amplifier forms an optical resonator. The subject of the invention is that the reflectance of the Bragg grating at the Bragg diffraction wavelength is greater than 60%.
