Silicon photonic optical-electrical-optical converters based on load-resistor and current-injection operation
Masaya Arahata, Shota Kita, Akihiko Shinya +2
Optical-electrical-optical (OEO) converters are key primitives for low-latency, energy-efficient photonic computing because they enable nonlinear activation and optical signal rege…
