Abstract: | Based on the physical fact that a laser containing a gain medium with homogenous line broadening oscillates at the wavelength which requires the smallest threshold gain due to the mode competition effect, after taking into account the wavelength-depended reflectivity distribution profile of a fiber Bragg grating, the oscillation wavelength λl of fiber Bragg grating semiconductor lasers has been investigated theoretically. The results show that the laser oscillation wavelength λB is not fixed at the Bragg reflection wavelength λl of fiber Bragg grating, and the offset between λB and λl depends on the reflectivity distribution profile of fiber Bragg grating and the gain profile of semiconductor gain medium. |
