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…
Optoelectronic recurrent neural network using optical-electrical-optical converters with RC delay
Masaya Arahata, Shota Kita, Kazuo Aoyama +3
Optical neural network (ONN) has been attracting intense attention owing to their low latency and low-power consumption. Among the ONNs, optical recurrent neural network (RNN) enab…
Observing exceptional point degeneracy of radiation with electrically pumped photonic crystal coupled-nanocavity lasers
Kenta Takata, Kengo Nozaki, Eiichi Kuramochi +6
Controlling gain and loss of coupled optical cavities can induce non-Hermitian degeneracies of eigenstates, called exceptional points (EPs). Various unconventional phenomena around…
Monolithic CMOS-compatible zero-index metamaterials
Daryl I. Vulis, Yang Li, Orad Reshef +5
Zero-index materials exhibit exotic optical properties that can be utilized for integrated-optics applications. However, practical implementation requires compatibility with comple…
On-chip all-dielectric fabrication-tolerant zero-index metamaterials
Shota Kita, Yang Li, Philip Muñoz +5
Zero-index metamaterials (ZIMs) offer unprecedented ways to manipulate the flow of light, and are of interest for wide range of applications including optical cloaking, super-coupl…
