We report on the design and characterization of focusing-curved subwavelength grating
couplers for ultra-broadband silicon photonics optical interfaces. With implementation of …

A wavelength-division multiplexer with no polarization dependence is demonstrated. It is
based on an arrayed-waveguide grating fabricated with silica-based optical waveguides on …

We present ultracompact integrated optical echelle grating wavelength-division-multiplexing
(de) multiplexers for on-chip optical networks, fabricated using high-index-contrast silicon-on …

We present high-efficiency grating couplers for coupling between a single-mode fiber and
nanophotonic waveguides, fabricated both in silicon-on-insulator (SOI) and InP membranes …

Standard silicon photonic strip waveguides offer a high intrinsic refractive index contrast; this
permits strong light confinement, leading to compact bends, which in turn facilitates the …

We present the design and characterization of waveguide grating devices that couple visible-
wavelength light at λ= 674 nm from single-mode, high index-contrast dielectric waveguides …

Here, we present a compact, high-resolution, and ultrabroad-bandwidth arrayed waveguide
grating (AWG) realized in a silicon nitride (Si_3N_4) platform. The AWG has a cascaded …

Nanophotonic waveguides and components are promising for use in the large-scale
integration of photonic circuits. Coupling light between nanophotonic waveguides and a …

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 report the first experimental demonstration of a novel single-layer subwavelength grating
(SWG) that has> 500-nm-wide reflection spectrum from 1.12-1.62 μm and very high …
