LiNbO3 thin film ACP phase modulator for hybridly integrated ACP-OPLL

The first LiNbO3 thin film attenuated counter propagation (ACP) phase modulator is presented. The modulator demonstrates a Vπ of 2.5 V and a record 3 dB ACP modulator bandwidth of ∼1.8 GHz. It also demonstrated a lumped element response that is free of propagation delay. This device should be able t...

Zusammenfassung:	The first LiNbO3 thin film attenuated counter propagation (ACP) phase modulator is presented. The modulator demonstrates a Vπ of 2.5 V and a record 3 dB ACP modulator bandwidth of ∼1.8 GHz. It also demonstrated a lumped element response that is free of propagation delay. This device should be able to be integrated with external photodetectors to form a wideband ACP-optical phase lock loop.
