Abstract: Disclosed is a method and apparatus for optically modulating and transmitting source data. An optical comb comprising optical tones having a frequency spacing equal to Δf is generated by an optical comb generator. Selected ones of the optical tones in the optical comb are modulated according to the source data to produce a comb of modulated optical tones. At least one optical tone in the optical comb is frequency shifted by a frequency less than Δf to produce a frequency shifted unmodulated optical reference tone. The optical comb, the frequency shifted unmodulated optical reference tone and the comb of modulated tones are multiplexed onto at least one optical path.

In some implementations, adjusting the frequency of an output signal of the photonic oscillator further comprises adjusting at least one of an phase shifter in series with the amplifier, an optical fiber stretcher, or a bias voltage of a second amplifier. In one embodiment of the present invention, a photonic oscillator is provided including a laser and an optical modulator coupled to the laser. A lightwave delay path is coupled to the optical modulator. In some embodiments, dual lightwave delay paths are provided, such as a long loop delay path and a short loop delay path. A photodetector is coupled between the lightwave delay path and an amplifier. Typically, a bandpass filter is coupled between the amplifier and the modulating input of the optical modulator. A control circuit coupled to the amplifier is constructed so as to be capable of adjusting a bias power to the amplifier so as to shift a frequency of an output of the photonic oscillator. In some embodiments, the control circuit may include a frequency lock loop circuit.

Abstract: A method and apparatus for generating an arbitrary UWB waveform are presented. An optical comb generator generates a serial stream of optical tones and an optical beating tone. A serial-to-parallel converter receives the serial tones and converts them into parallel optical tones. A spatial light modulator receives the parallel optical tones, and independently adjusts at least one of the phase and amplitude of each to generate the components of an arbitrary waveform. Next, each one of a plurality of optical-to-electrical converters receives a parallel optical tone and the selected optical beating tone, which are beat with the optical beating tone, producing electrical notes, representing differences between each parallel optical tones and the optical beating tone. Each antenna element is connected to receive an electrical note and to launch a signal based thereon, such that the launched signals are superimposed to the arbitrary waveform signal.
