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…
On-chip room-temperature CW lasing from a III-V nanowire integrated with a Si photonic crystal platform
Masato Takiguchi, Takuro Fujii, Hisashi Sumikura +3
We report the demonstration of continuous-wave (CW) lasing at room temperature from a III-V semiconductor nanowire integrated into a Si photonic crystal (PhC) cavity. Conventional…
Programmable Photonic Unitary Processor Enables Parametrized Differentiable Long-Haul Spatial Division Multiplexed Transmission
Mitsumasa Nakajima, Kohki Shibahara, Kohei Ikeda +4
The explosive growth of global data traffic demands scalable and energy-efficient optical communication systems. Spatial division multiplexing (SDM) using multicore or multimode fi…
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…
