  • Optical domain wideband RF spectrum analyzer/channelizer based on third-order nonlinear mixing
    Patent number: 8611759
    Abstract: An optical domain spectrum analyzer/channelizer employs multicasting of an analog signal onto a wavelength division multiplexing grid, followed by spectral slicing using a periodic optical domain filter. This technique allows for a large number of high resolution channels. Wideband, 100% duty cycle, spectrum analysis or channelization is made possible permitting continuous time wideband spectral monitoring. The instantaneous bandwidth of the spectrum analyzer/channelizer is equal to the full radio frequency bandwidth of the analyzer/channelizer.
