The influence of magnetic field on confined exciton-polariton modes inside a semiconductor microcavity is discussed. The three-dimensional confinement for exciton-polaritons is achieved by the mesa structures confining the photonic part of polaritons. We o ...
Recently developed, highly effective technologies enabling slow light propagation as a tunable feature in photonic devices, are reviewed. Several applications in ICT are also demonstrated. Controlling the group velocity of light offers a broadband solution ...
Like photonic crystals have revolutionized the way of manipulating optical waves at the sub-micron scale, phononic crystals have more recently played similar decisive role for sound waves, or more generally elastic waves. Then, the idea of coupling light a ...
The goal of this project is to demonstrate by simulations the relevance of fabricating nanowired structures for integrated optical applications. Indeed, subwavelength nanostructures present the advantage of guiding consistently the light, while having also ...
Following rapid developments in biotechnology and medicine, optical sensing promises to be extremely important in various applications such as drug discovery, environmental monitoring, etc. Refractive index (RI) based optical sensing is straightforward to ...
Femtosecond laser manufacturing combined with chemical etching has recently emerged as a flexible platform for fabricating three-dimensional devices and integrated optical elements in glass substrates. Here, we demonstrate an optically transparent micro-ac ...
Photonic crystal (PhC) devices owing to their strong confinement of electromagnetic energy are considered to be excellent candidates for on chip optical trapping of dielectric or biological particles in the nanometer range. In this work, we study and prese ...
