The design of an opto-electronic loop that drives a harmonic mode-locked laser to produce a beat pattern signal to act as a high precision clocking protocol in both the optical and electronic regimes.
Inside of every piece of modern electronic technology lays a clock. Intended to coordinate and synchronize spatially separated operations within in a circuit or across a communications channel, these precision clocks are the enabler of all computational protocols. Traditionally, being that computers are based off of electronic circuitry, electronic oscillators are used to generate these precision sine wave signals. With the recent proliferation of optical information transfer, however, the need for optical clocking systems has surfaced, especially in the communications sector.
To address this need, researchers at UCF have developed a method for producing a stable optical clock signal of more than 12.4GHz using the classical wave phenomenon of frequency beating. Commonly, where an optical clock is needed, an electronic one is as well, and the invention proposed herein offers both simultaneously. The design presented here produces a beat note created through the paring of two mode-locked pulses.
