We propose and demonstrate a novel system configuration to simplify a central station in a millimeter-wave radio-on-fiber system. Optical wavelength paths are switched using tunable light sources and required devices can be reduced.
Resonant filters in waveguides with vertical gratings have been realized on a silicon-on-insulator wafer. Two identical uniformly distributed Bragg reflectors with vertical gratings are separated by a quarter wavelength phase offset. Experimental studies show a broad stopband and a narrow transmission band which shifts with changing substrate temperature that is also illuminated by an external laser...
In this paper, we extend our approach to implement a resonant filter and resonant modulator using lithographically defined nanostructures on sidewalls of a waveguide in silicon on insulator (SOI) material system
