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 demonstrate a fully etched, continuously apodized fiber-to-chip surface grating coupler
for the first time (to our knowledge). The device is fabricated in a single-etch step and …

A 3D bi-directional mode expansion propagation algorithm based on Fourier series using
trigonometric functions is briefly described. Nonlinear complex coordinate transformations …

In integrated photonic circuits, the refractive-index contrast is usually set by the choice of the
material platform. For example, for silicon photonic circuits operating at a wavelength near l …

Surface plasmons-polaritons (or briefly, surface plasmons, SP) have been intensively
investigated as potential information carriers for ultra-small photonic (plasmonic) devices …

Over the last fifteen years, a series of theoretical and experimental investigations have
demonstrated the usefulness of circular geometries to tailor second-order nonlinear optical …

The search for new photonic materials has defined important directions for controlling optical
dispersion. The discovery of photonic crystals1 led to dispersion engineering and also to …

Silicon photonic interconnects represent a possible solution to the problems associated with
scaling electrical interconnects to higher data rates. Defectmediated optical detectors …
