    摘要： An apparatus having a topology that allows building complicated optical programmable arrays useful for manipulating the phase and/or amplitude of an optical signal. Sophisticated filtering and other optical signal processing functionality can be programmed into the array after a chip containing the array has been fabricated. This programming capability is analogous to that of electronic field programmable gate arrays (FPGA's). Apparatus described herein will provide a powerful tool for processing optical signals or very broadband electrical signals.

    摘要： A signal receiver, such as an RF-matched filter receiver, includes an optical source (e.g. a mode-locked laser) providing an optical signal, and a first optical modulator to modulate the optical signal with a received RF signal and provide a modulated optical signal. A second optical modulator modulates the modulated optical signal with a reference signal and provides a twice modulated optical signal. The modulators may be Mach-Zehnder Modulators (MZM) and/or Indium Phosphide (InP) modulators. An optical detector receives the twice modulated optical signal and provides a detected signal, and a processing unit receives the detected signal and extracts or measures cross-correlation between the received RF signal and the reference signal.
