Abstract:
1. A photonic circuit, comprising: a circuit input configured to receive radio frequency (RF) signals; a modulator coupled to the circuit input and configured to receive the radio frequency (RF) signals; an optical source coupled to the modulator and configured to provide optical signals, the modulator and the optical source being arranged to work together to modulate the radio frequency (RF) signals received from the circuit input onto the optical signals provided by the optical source; a filter array coupled to the optical source and configured to receive the optical signals, the filter array including a plurality of filters configured to channelize the optical signals received from the optical source in order to provide channelized optical signals; and a circuit output coupled to the filter array and configured to receive the channelized optical signals, wherein two or more of the modulator, the optical source, or the filter array are combined on a single monolithic chip so that they generally experience iso-thermal conditions, and the photonic circuit provides for the transmission of radio frequency (RF) content in the optical domain.
