Abstract Photon’s effective mass is an important parameter of an optical cavity mode, which determines the strength of light-matter interaction. Here, we propose a novel method for controlling the photon’s effective mass by using coupled photonic

We propose an efficient planar all-Si internal photoemission photodetector operating at the telecommunication wavelength of 1550 nm and numerically investigate its optical and electrical properties. The proposed polarization-sensitive detector is com

We explore the use of a modal expansion technique, Fourier modal method (FMM), for investigating the optical properties of vertical cavities employing high-contrast gratings (HCGs). Three techniques for determining the resonance frequency and quality

For silicon photonics, specifically chip-level optical interconnects, an ultrahigh-speed low-energy-consuming laser that can be integrated onto a silicon (Si) wafer is an ideal element. Here, we report on a hybrid Si-on-chip micro-cavity laser struct
