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 …

It is a remarkable and straightforward approach to customize the dispersion and nonlinear
properties of the photonic devices without varying the composition of the material by …

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 use subwavelength gratings (SWGs) to engineer the refractive index in microphotonic
waveguides, including practical components such as input couplers and multiplexer circuits …

We present several fundamental photonic building blocks based on suspended silicon
waveguides supported by a lateral cladding comprising subwavelength grating …

Photonic filters are playing a very important role in many applications, including optical
interconnects as well as optical sensing. As silicon photonics has provided a very attractive …

In this Letter, we report suspended silicon waveguides operating at a wavelength of 7.67 μm
with a propagation loss of 3.1±0.3 dB/cm. To our knowledge, this is the first demonstration of …

We report on the design, simulation and experimental demonstration of a new type of
waveguide crossing based on subwavelength gratings in silicon waveguides. We used 3D …

Periodic structures with a sub‐wavelength pitch have been known since Hertz conducted his
first experiments on the polarization of electromagnetic waves. While the use of these …

We explore, to the best of our knowledge, the potential of diffractionless subwavelength
grating waveguides for sensing applications. We show that by subwavelength patterning of …
