Abstract
e review recent work on narrowband orthogonally polarized optical RF
single sideband generators as well as dual-channel equalization, both
based on high-Q integrated ring resonators. The devices operate in the
optical telecommunications C-band and enable RF operation over a range
of either fixed or thermally tuneable frequencies. They operate via
TE/TM mode birefringence in the resonator. We achieve a very large
dynamic tuning range of over 55 dB for both the optical
carrier-to-sideband ratio and the dual-channel RF equalization for both
the fixed and tunable devices.
