Abstract
Variable optical carrier reduction via the use of a Si3N4 ring
resonator notch filter with tunable extinction ratio is demonstrated in a 10
GHz radio-over-fiber system for improving the modulation efficiency. The
extinction of the filter notch is tuned with micro-heaters, by setting the
Mach-Zehnder coupler of the ring. Experimental results showing a
modulation depth improvement of up to 20 dB are provided
