Tilted-potential photonic crystal cavities for integrated quantum photonics

Benjamin Dwir, Elyahou Kapon, Alok Rudra, Antoine Maxime Delgoffe, Bruno Marie Dominique Rigal, Alexey Lyasota, 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 ...

GaN Quantum Dots for Room Temperature Excitonic Physics

Sebastian Pascal Tamariz Kaufmann

Quantum dots (QDs) are the result of quantum confinement in the three spatial directions, as such they exhibit remarkable properties, of which the most important is perhaps the absence of a continuum of states. The allowed energetic levels are discrete, si ...

DORI Reveals the Influence of Noncovalent Interactions on Covalent Bonding Patterns in Molecular Crystals Under Pressure

Laurent Alexis Clément Vannay, Anne-Clémence Corminboeuf, Berend Smit, Senja Dominique Barthel, Amber Kashan Mace, Benjamin André René Meyer

The study of organic molecular crystals under high pressure provides fundamental insight into crystal packing distortions and reveals mechanisms of phase transitions and the crystallization of polymorphs. These solid-state transformations can be monitored ...

Spontaneous Formation of CdSe Photoluminescent Nanotubes with Visible-Light Photocatalytic Performance

Martinus Gijs, Virendra Kumar Parashar, Xiaopeng Huang

Two-dimensional (2D) colloidal CdSe nanocrystals (NCs) with precise atomic-scale thickness have attracted intensive attention in recent years due to their optical properties and quantum confinement effects originating from their particular band structure. ...

Slow light engineering in resonant photonic crystal line-defect waveguides

Maliheh Khatibi Moghaddam, Romain Christophe Rémy Fleury

Slow light plays an outstanding role in a wide variety of optical applications, from quantum information to optical processing. While slow optical guiding in photonic crystal waveguides is typically based on Bragg band gaps occurring in non-resonant photon ...

Site-controlled quantum dots integrated with photonic crystal waveguides and cavities

Bruno Marie Dominique Rigal

Quantum mechanics did not only deeply transform our world view down to a philosophical level, it is also expected to be key ingredient of future so-called quantum technologies. Indeed, quantum properties of matter such as isolated single particles or entan ...

Light-Matter Interaction in III-Nitride Waveguides: Propagating Polaritons and Optical Gain

Joachim Armand Simonne Ciers

III-nitride waveguides featuring AlInN claddings and GaN/AlGaN quantum wells (QWs) offer promising perspectives for applications in many fields of short-wavelength photonics. Thanks to their nearly lattice-matched nature, these structures exhibit an excell ...

Light Confinement and Nonlinear Light-Matter Interaction in Semiconductor Photonic Crystal Cavities

Mohamed Sabry Abdel-Aliem Mohamed

The ability to control and manipulate light is a fundamental aspect that is at the very core of the development of integrated photonic circuits. It is desirable to achieve such control down to a scale that is comparable to or smaller than the wavelength of ...

Spatial and Morphological Control of Cyanine Dye Thin Films

Nicolas Alexandre Serge Leclaire

Cyanine dyes are organic semiconductor compounds with light absorption and emission properties useful for emerging technologies such as solar cells and light-emitting devices. The characteristics of these materials in the solid state depend on their organi ...
