Optical generation of millimeter-waves using a dual-polarization emission external cavity diode laser

We report on the generation of millimeter-waves by heterodyne mixing of two wavelength tunable laser modes emitted simultaneously from a single diode laser operating in a two-arm external cavity. The modes are in the 1.55 /spl mu/m range, one of them vibrates in TE and the other in TM polarization. We have measured beat-frequencies from 1 to 22 GHz, where… CONTINUE READING
