Spatial quantum-interference landscapes of multi-site-controlled quantum dots coupled to extended photonic cavity modes

Elyahou Kapon, Alok Rudra, Benjamin Dwir, Alessio Massimiliano Davide Miranda

A compact platform to integrate emitters in a cavity-like support is to embed quantum dots (QDs) in a photonic crystal (PhC) structure, making them promising candidates for integrated quantum photonic circuits. The emission properties of QDs can be modifie ...

Spatial Avoided Crossing in Optical Emission of Site-Controlled Pyramidal Quantum Dots in Photonic Crystal Cavities

Elyahou Kapon, Alok Rudra, Benjamin Dwir, Alessio Massimiliano Davide Miranda

Interactions of site-controlled quantum dots with a high-order cavity mode of an L7-type photonic crystal cavity are resolved spatially and spectrally. We observed a spatial avoided crossing in polarization-resolved optical emission of quantum dots. ...

Mode Interference Effect in Optical Emission of Quantum Dots in Photonic Crystal Cavities

Elyahou Kapon, Alok Rudra, Benjamin Dwir, Alexey Lyasota, Clément William Tendaï Jarlov, Milan Calic, Alessio Massimiliano Davide Miranda

Radiation properties of a pointlike source of light, such as a molecule or a semiconductor quantum dot, can be tailored by modifying its photonic environment. This phenomenon lies at the core of cavity quantum electrodynamics (CQED). Quantum dots in photon ...
