Abstract:

We have pursued a vigorous program of experimental and theoretical research on a novel method of frequency division based on an optical parametric oscillator OPO. We have successfully demonstrated optical frequency division in a nearly degenerate KTP OPO that is highly efficient and tunable. The difference frequency of the two subharmonic outputs of the OPO was phase locked to a 12-GHz microwave source with a residual phase noise spectral density of 0.3 mradVH-z. More recently the use of a THz optical frequency comb permitted the OPO to be phase locked at a difference frequency of 665 GHz. We have studied a number of potential applications including optical frequency counting for frequency standards and multi-THz optical frequency comb generation for optical communications.
