40 GHz optical-millimetre wave generation with a dual polarisation distributed feedback fibre laser

Optical-millimetre wave generation in a dual polarisation mode distributed feedback fibre laser is demonstrated. by fabricating the laser in an elliptical core erbium doped fibre, the birefringence increases the frequency separation of the two polarisation modes, enabling a 40GHz heterodyne signal to be generated with a 3dB beat linewidth of 900Hz.
