This paper proposes a wavelength-parallel photonic tensor core by exploiting multiple free spectral ranges (multi-FSRs) of the microring resonator crossbar array architecture. As an example, a four-FSR 4×4 crossbar array is designed and simulated.

We perform wafer-level testing of perfectly vertical grating couplers in a c-Si 193nm DUV immersion lithography process. We designed single polarization grating couplers using the adjoint method and experimentally obtain an insertion loss of 1.91dB,

Recently, silicon photonics foundries started providing access to new dielectric stacks which can be utilized to reduce optical I/O losses. For example, in a hybrid c-Si/SiN platform, inverse design techniques can be used to create novel dual layer g

The rate of spontaneous emission from an optical emitter can be greatly enhanced using a metallic optical antenna at the penalty of efficiency. In this paper we propose a metal-dielectric antenna that eliminates the tradeoff between spontaneous emiss
