Abstract:
A model for calculating the parameters of a laser diode with an external fibre cavity containing a fibre Bragg grating (FBG) is presented. It is shown that by using this model, it is possible to obtain single-mode lasing by neglecting the spectral burning of carriers. The regions of the laser-diode current and temperature and the FBG temperature in which the laser can be tuned to the D2 line of cesium are determined experimentally.
