Paper Abstract

Wavelength stability with respect to temperature for Fiber grating external cavity semiconductor lasers (FG-ECL) is analyzed theoretically. It is found that the use of temperature insensitive fiber grating can decrease the thermal induced wavelength shift, but simultaneously, reduce the temperature interval of mode hopping. Furthermore, a method is proposed to suppress the thermal induced mode hopping and wavelength shift in FG-ECL.
