This article presents a photonics-assisted radar jamming system utilizing two cascaded Mach-Zehnder modulators, capable of performing two distinct jamming functions with a simple architecture. With 0°-180° phase modulation, the system effectively eliminates the central false target, and significantly increases the number of false targets via composite jamming of comb spectrum modulation and phase ...Show More
We demonstrate broadband Silicon-Nitride asymmetric Mach-Zehnder interferometer temperature sensor showing near 40 pm/K sensitivity from $25^{\mathrm{o}}\mathrm{C}$ to $85^{\mathrm{o}}\mathrm{C}$ in S+C+L band, which is two times larger than conventional Silicon-Nitride temperature sensors. The proposed sensor only needs single lithography for the sensing unit, without introducing negative thermo-...Show More

On-chip optical neural networks (ONNs) have recently emerged as an attractive hardware accelerator for deep learning applications, characterized by high computing density, low latency, and compact size. As these networks rely heavily on massive matrix multiplication, photonic matrix computing cores become crucial components for on-chip ONNs, which harness the degree of freedoms (DOFs) in photonics...Show More
Integrated optics hold great potential to accelerate deep learning tasks with high clock rates, parallelism and low-loss data transmission. Silicon photonic integrated circuits can perform large-scale and low-power-consuming optical linear operations by using weighting mechanism through linear optics.

1 × 2 power splitter is the fundamental component of passive optical network (PON) with bus or ring topology. In existing PON architecture, uplink and downlink wavelengths distribute in a large wavelength range from O-band to L-band, which requires power splitter used in PON having a bandwidth of around 300 nm to cover both uplink and downlink wavelengths. Compared with currently used passive powe...Show More
The electro-absorption modulated laser (EML) chip-on-carrier (COC) submodule has a complex equivalent circuit model, making it challenging to characterize the EML parameters directly.
