A distributed feedback ΓΏbre laser is realised with a phase-shifted ΓΏbre Bragg grating. Dual-mode operation is obtained by means of linear birefringence for heterodyne generation of optical microwave signal. The two modes, operating in the same cavity produce a beat signal with exceptionally low-phas
