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 ...

Time-resolved physical spectrum in cavity quantum electrodynamics

Alexey Lyasota

The time-resolved physical spectrum of luminescence is theoretically studied for a standard cavity quantum electrodynamics system. In contrast to the power spectrum for the steady state, the correlation functions up to the present time are crucial for the ...

Remote excitation between quantum emitters mediated by an optical Fano resonance

Elyahou Kapon, Alok Rudra, Benjamin Dwir, Antoine Maxime Delgoffe, Alexey Lyasota, Alessio Massimiliano Davide Miranda

Remote coupling between quantum emitters is of great importance for constructing quantum networks. Conventionally, this can be achieved via photon exchange by incorporating the quantum emitters in a waveguide or a large cavity. However, such photonic struc ...

Theory of Fano effect in cavity quantum electrodynamics

Alexey Lyasota

We propose a Markovian quantum master equation that can describe the Fano effect directly, by assuming a standard cavity quantum electrodynamics system. The framework allows us to generalize the Fano formula, applicable over the weak- and strong-coupling r ...

Integrated Quantum Photonics using Site-Controlled Quantum Dots and Tailored-Potential Photonic Crystals

Elyahou Kapon, Alok Rudra, Benjamin Dwir, Antoine Maxime Delgoffe, Alexey Lyasota, Alessio Massimiliano Davide Miranda, Yi Yu

We demonstrate several integrated photonics structures incorporating site-controlled quantum dots and photonic crystal cavities with tailored mode structures. Optimal designs for single photon extraction, routing and switching are presented and discussed. ...

Tilted-potential photonic crystal cavities for integrated quantum photonics

Elyahou Kapon, Alok Rudra, Benjamin Dwir, Antoine Maxime Delgoffe, Alexey Lyasota, Bruno Marie Dominique Rigal, Alessio Massimiliano Davide Miranda

We propose and investigate a new type of photonic crystal (PhC) cavity for integrated quantum photonics, which provides tailored optical modes with both confined and extended spatial components. The structures consist of elongated PhC cavities in which the ...

Limiting the Spectral Diffusion of Nano-Scale Light Emitters using the Purcell effect in a Photonic-Confined Environment

Elyahou Kapon, Alok Rudra, Benjamin Dwir, Alexey Lyasota, Clément William Tendaï Jarlov

Partial suppression of the spectral diffusion of quantum dot (QD) excitons tuned to resonance of a nano-photonic cavity is reported. The suppression is caused by the Purcell enhancement of the QD-exciton recombination rate, which alters the rate of chargin ...

Interaction between site-controlled quantum dot systems and photonic cavity structures

Alexey Lyasota

The goal of this thesis was to investigate light-matter interaction in nanophotonic devices based on site-controlled pyramidal quantum dots (QD) in photonic crystal (PhC) cavities. These QDs provide position and spectral control, which is hardly achievable ...
