On-Chip Photonic AI Accelerator

Biological neuron and its photonic counterpart — synapse, dendrites, soma, and axon mapped to on-chip components.

Integrated photonic time-multiplexed reservoir computing architecture at 1550 nm with MZM nonlinear node and delay-line feedback.

NRMSE vs. number of virtual nodes on the NARMA-10 benchmark — reservoir+LR reaches 0.21, well below the linear baseline.

Word error rate on spoken digit recognition (FSDD) drops to 1.5% — a six-fold improvement over the linear baseline.

Silicon-on-insulator optical phased array with 48 linearly apodized grating antennas for on-chip LiDAR.

3D radiation pattern, single-antenna transmission over 1500–1700 nm, and azimuth/elevation beam cuts.

Continuous beam steering over 62° field of view at 1550 nm with sidelobe suppression exceeding 85 dB.

Main-lobe angle vs. voltage — electrical steering across azimuth and elevation with tunable phase shifters.

1×13 channel Si₃N₄ arrayed waveguide grating (AWG) fabricated on a 300 mm silicon photonics platform.

AWG operating principle — wavelength-dependent path length differences separate input channels at the output focal plane.

Measured transmission across C+L bands (1500–1620 nm) — 0.92 dB insertion loss, –37.5 dB crosstalk, 20 nm FSR.

4-bit photonic analog-to-digital converter — cascaded MZI arms with distinct lengths give direct binary encoding.
