Continuously tunable orthogonally polarized RF optical single sideband generator based on cascaded micro-ring resonators

摘要

We demonstrate an orthogonally polarized optical single sideband (OP-OSSB) generator based on dual cascaded micro-ringresonators (MRRs). We achieve a large tuning range of the optical carrier to sideband ratio of up to 57.3 dB. The operation RFfrequency of the OP-OSSB generator can also be continuously tuned with a 21.4 GHz range via independent thermal control ofthe two MRRs.
