Real photonic waveguides are affected by structural imperfections due to fabrication
tolerances that cause scattering phenomena when the light propagates through. These …

As the most fundamental unit of photonic integration, optical waveguides offer the possibility
of develo** efficient and practical photonic chips by facilitating the on‐chip integration of …

We report on the experimental demonstration and analysis of a new waveguide principle
using subwavelength gratings. Unlike other periodic waveguides such as line-defects in a …

We propose the use of slow-light, band-edge waveguides for compact, integrated, tunable
optical time delays. We show that slow group velocities at the photonic band edge give rise …

Something very surprising has been happening in photonics recently: the same foundries
and processes that were developed to build transistors are being repurposed to build chips …

A fast, effective process using hydrogen annealing is introduced to perform profile
transformation on silicon-on-insulator (SOI) and to reduce sidewall roughness on silicon …

We report optical waveguides up to one meter long with 0.026 dB/cm loss fabricated in a
300nm thick SOI CMOS process. Combined with tight bends and compact interlayer grating …

Applied quantum optics stands to revolutionise many aspects of information technology,
provided performance can be maintained when scaled up. Silicon quantum photonics …

Evanescent field sensors have shown promise for biological sensing applications. In
particular, Silicon-on-Insulator (SOI)-nano-photonic based resonator sensors have many …

We study guided modes in a conductor-gap-dielectric (CGD) system that includes a low-
index dielectric gap layer of deep sub-wavelength thickness sandwiched between a …
