Paper Abstract

We generated low phase noise mm-wave electrical signals of sub-kHz linewidth from a single 1550 nm diode laser with a linewidth in excess of 1 MHz. Our approach uses a phase modulator to generate a multiline spectrum from a single mode laser, which is filtered to pass only a pair of spectral lines. Interference between the lines on the active area of a photodetector produces an electrical signal that can be set between 4 and 60 GHz. This technique has the advantage that the electrical linewidth can be much narrower than the laser linewidth due to common mode rejection of frequency noise between the interfering sidebands, and that relatively low frequency electronics can be used to generate the sideband spectrum.
