Abstract

We have previously described an integrated symmetric self-electrooptic effect device (S- SEED) that acts as a bistable optical memory element with individual set S and reset R inputs and complementary outputs (optical S-R latch).¹ New measurements show switching speeds down to 40 ns, contrast ratios of 2.9:1, and total optical switching energies of 16 fJ/μm². We demonstrate the cascadability of these devices in a photonic ring counter and demonstrate a logic gate that performs nor, nano, or, and and functions.
