A review of the properties of silicon-based two-dimensional (2D) photonic crystals is given,
essentially infinite 2D photonic crystals made from macroporous silicon and photonic crystal …

High-quality factor (Q) photonic nanocavities that strongly confine photons in volumes of
optical-wavelength dimension are attracting much attention in various fields, including …

High-index-contrast, wavelength-scale structures are key to ultracompact integration of
photonic integrated circuits. The fabrication of these nanophotonic structures in silicon-on …

Recently, strongly modulated photonic crystals, fabricated by the state-of-the-art
semiconductor nanofabrication process, have realized various novel optical properties. This …

We report the design and testing of an SOI-based photonic integrated circuit containing two-
dimensional membrane-type photonic crystal waveguides. The circuit comprises spot-size …

We pursued the extremely low loss of photonic-crystal waveguides composed of a silicon
slab with high resistivity (20 kΩ-cm) in the terahertz region. Propagation and bending losses …

Formulas are presented that provide clear physical insight into the phenomenon of extrinsic
optical scattering loss in photonic crystal waveguides due to random fabrication …

We demonstrate a novel polarization splitter based on a two-dimensional grating etched in a
silicon-on-insulator waveguide. The device couples orthogonal modes from a single-mode …

We propose an ultrahigh quality factor (Q) photonic crystal slab nanocavity created by the
local width modulation of a line defect. We show numerically that this nanocavity has an …

Although the first lasers invented operated in the visible, the first on-chip devices were
optimized for near-infrared (IR) performance driven by demand in telecommunications …
