Abstract :
A simple multiplexing scheme is proposed and demonstrated with the capability to interleave optically modulated 37.5-GHz radio channels in a dense-wavelength-division-multiplexed fiber-radio system with 25-GHz wavelength spacing, and also enable a carrier subtraction technique that improves the overall link performance by reducing the carrier-to-sideband ratio of the multiplexed channels. The proposed scheme is realized by the use of an arrayed waveguide grating having multiple optical loop-backs between the input and the output ports.
