About the session

We experimentally demonstrate a Bragg-grating-based modulator operating in reflection with low loss and without a circulator by using mode conversion and an asymmetric Y-branch. With a compact footprint of 240μm, we demonstrate OOK up to 30 Gbit/s with an estimated switching energy of 150 fJ/bit.
