✦ Synopsis

A distributed feedback ÿbre laser is realised with a phase-shifted ÿbre 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-phase noise. The linewidth of the resulting microwave signal obtained is less than 1 kHz.
