Abstract

We have demonstrated stabilization of a fiber-optic Mach–Zehnder interferometer, with a centimeter-scale path difference, to the transmission minimum for the carrier wave of a frequency-modulated laser beam. A time-averaged extinction of 32 dB, limited by the bandwidth of the feedback, was maintained over several hours. The interferometer was used to remove the carrier wave from a 780 nm laser beam that had been phase modulated at 2.7 GHz.

  14. In our experiment, the light used to generate the locking signal was taken from the laser beam before the electro-optic phase modulator and hence contained only a single frequency component. If instead the sidebands are generated, for example, by modulation of the laser supply current, they will remain present in the monitor beam and could lead to additional features and false lock points. However, provided that the sidebands are separated from the carrier by integer multiples of ωs, they will merely change the magnitude of the error signal and not alter its form, although in the case of strong modulation, the sign of the error signal may be reversed.
