- Highly-optomechanically-coupled active and passive optical microcavities, BP.PD
Abstract
This project proposes the development of active and/or passive optomechanical microcavities made of III-V semiconductor alloys with high optomechanical coupling strength. With optimized structures, our aim is to study and improve the optomechanical coupling using innovative designs and materials. Moreover, in the active case, we plan to investigate and demonstrate the coupling between t...
- Coupled active microresonators on hybrid Si/III-V platform, BP.DR
Abstract
A new paradigm on Photonics is the total integration of actives and passives devices, jointly with electronic ones, at the same chip. In this context, ultracompact high functional devices represent a key concept for a new era of telecommunications development. In this work, we propose the design, fabrication and characterization of tunable microlasers on Si - InGaAsP/InP hybrid platform...

Abstract
We shall develop microdisk resonators using confinement of "Whispering Galery Modes" type modes by the partial oxidation of AlxGa1-xAs layers. For this, initially we will develop an apparatus for selective oxidation of layers with AlxGa1-xAs alloys in epitaxial structures grown on GaAs substrates. The selective oxidation process developed will be characterized considering parameters of ...

Abstract
Optomechanical systems has been demonstrated recently, mainly in GHz frequencies. Based on this, we propose the development of active devices with light emission modulated by optomechanical oscillations. We suggest fabrication of double microdisk, based on double heterostructure InGaAsP/InP, and we will explore the interaction between the effects of photons emission due to recombination...

- Fabrication of lasers with Coupled- Microresonators-Selective-Mirrors on heterogeneously integrated III-V/Si platform, BE.EP.DR
Abstract
We propose a 1-year project for the fabrication and characterisation of semiconductor lasers employing wavelength selective of coupled microring resonators as mirrors on a heterogeneously integrated InP (InGaAsP)/SOI platform in collaboration with Prof. Dr. Ir. Gunther Roelkens (University of Ghent, Belgium). All Si waveguides and optical cavities will be fabricated at IMEC (Belgium) wi...
- Active devices exploiting capacitively-inducedc free-carrier effects in silicon waveguides, BE.EP.DR
Abstract
This project will involve theoretical and experimental characterization of capacitively-induced free-carrier effects in silicon waveguides. We anticipate our results to show that, in addition to being a critical factor in the analysis of such active Si photonics devices as capacitively-driven silicon modulators, this effect should also be taken into account when considering the propagat...

Abstract
We propose the experimental investigation of effects of a gain medium in an optomechanical cavity based on III-V materials, i.e., demonstrate an optomechanical laser. The project is based on the incorporation of gain medium - essentially quantum wells and/or quantum dots - to optomechanical cavities in a joint effort for the investigation of active optomechanical devices. This proposal ...
