This work presents a “half-etch” horizontal slot waveguide design based on SiN, where only the upper SiN layer is etched to form a strip that confines the mode laterally. The numerical modeling, fabrication, and characterization of passive wavegu

Many applications require colored surfaces while maximizing photons to pass through with no optical losses. As the perceived color depends on the spectral content and the number of reflected photons for each wavelength, it is necessary to consider no

A new theoretical methodology enabling the determination of the complex refractive index has been developed and explored; it only requires to use a classical set-up to control the incident angle, without the need for a polarizer. As a proof of concep

The realization of high sensitivity integrated photonic sensors requires strong light/matter interaction. Unfortunately, in an optical waveguide, only the evanescent part of the mode interacts with the cladding medium under test. In this context, we
