Tunable External Cavity Semiconductor Laser with Fiber Bragg Grating as Feedback
An external cavity semiconductor laser configuration, which employs fiber grating as feedback is reported in this paper. The fiber grating is fabricated by UV light exposure, with reflectivity of 50%. At injection current of 50 mA, output is over 1 mW and the MSR is 42 dB. The laser wavelength is tuned by applying strain along the fiber grating and by heating the fiber grating. With the applying-strain method, the tuning range of 2 nm is obtained.
