Over the last 20 years, silicon photonics has revolutionized the field of integrated optics,
providing a novel and powerful platform to build mass-producible optical circuits. One of the …

Dedicated multi-project wafer (MPW) runs for photonic integrated circuits (PICs) from Si
foundries mean that researchers and small-to-medium enterprises (SMEs) can now afford to …

Electrical interconnects are becoming a bottleneck in the way towards meeting future
performance requirements of integrated circuits. Moore's law, which observes the doubling …

We present a theoretical optimisation of 1D apodized grating couplers in a “pure” Silicon-On-
Insulator (SOI) architecture, ie without any bottom reflector element, by means of a general …

Visible wavelengths of light control the quantum matter of atoms and molecules and are
foundational for quantum technologies, including computers, sensors, and clocks. The …

We design and fabricate a low-loss silicon photonic two-dimensional grating coupler that
serves to couple light between standard single-mode fibers and single-mode waveguides in …

A metal-based one-dimensional grating coupler on an x-cut lithium-niobate-on-insulator
wafer structure for a polarization-independent fiber interface is designed and demonstrated …

We have designed a polarization-splitting grating coupler (PSGC) in silicon-on-insulator
(SOI) that has 1.2? dB peak loss in numerical simulations, which is the best simulated …

Polarization-diversity couplers are low-cost industrially-scalable passive devices that can
couple light of unknown polarization from a telecom fiber-mode to a pair of TE-polarized …

Integrated photonics is a promising route toward high-performance next-generation ICT and
sensing devices. Although fiber-packaging is perhaps the most widely discussed obstacle to …
