Abstract
A photonic switch device accepts a data modulated RF signal and outputs the data modulated RF signal or a frequency converted version thereof at one or more outputs of the switch device. Tunable laser(s) is/are controlled to cause peak wavelength(s) of the optical signal(s) emitted therefrom. An EOM receives the accepted data modulated RF signal and optical signal(s) produced using the tunable laser(s), and the EOM outputs an optical data signal modulated to include the data modulated RF signal. A WDM receives the optical data signal output by the EOM and the optical data signal received by the WDM demultiplexer is output at one or more outputs thereof based on peak wavelength(s) of the optical data signal. Photodetectors optically coupled to respective outputs of the WDM demultiplexer convert optical signals back to electrical signals. Related methods and system are also described herein.
