Abstract

A photonic oscillator can produce a multifrequency optical signal having a spectrum that includes regularly spaced spectral lines. A photodetector can convert the multifrequency optical signal to a multifrequency electrical signal having a spectrum that includes the regularly spaced spectral lines. A bandpass filter can attenuate all but one spectral line of the spectrum of the multifrequency electrical signal to form a single-frequency electrical signal having leading/trailing edges that have the same precision as the photonic oscillator. A continuous-wave laser can lock to the multifrequency optical signal and produce a continuous-wave optical signal at a wavelength precisely locked to the photonic oscillator. A data encoder/decoder can modulate/demodulate a data stream onto/from the continuous-wave optical signal at a data rate of the single-frequency electrical signal. The modulated optical signal can be clocked with the leading/trailing edges of the single-frequency electrical signal.
