Project 1: Pulse laser deposition lift-off based integration for nonlinear applications
Pulsed Laser Deposition is a very promising technics for integrated optics since it can provide high quality materials and micro structuration without etching. In this topic, we want to fully explore the potential of these methods for different integrated devices (operating mainly around telecom wavelength but also in the mid-infrared), like etched less waveguides, rare-earth doped materials for gain or wavelength conversion-on-chip, Yttria-Stabilized Zirconia for non-linear optics applications.
Project 2: Novel Nonlinear optical devices for bio-chemical detection
Detection of (bio-) chemicals is of utmost importance in a broad range of applications, from bio-sensing to environmental monitoring. This endeavour requires new concepts with emphasis towards the IR spectral domain where compounds have a distinct fingerprint.The project aims at conceiving, manufacturing (exploiting both nano manufacturing capabilities in Lyon and Melbourne) and characterising new nonlinear integrated devices, exploiting quadratic and third order nonlinear materials.
Project 3: Reconfigurable Mid-IR broadband nonlinear sources
The mid infrared range (between 3 and 15 um) wavelength domain is gaining a significant momentum across a whole range of applications from highly sensitive (bio-) chemical sensors for security, industrial and environmental monitoring. This project aims at creating reconfigurable on-chip nonlinear broadband mid-IR sources, eg. COMBs and supercontinuum, with electrically-controlled ‘on-demand’ properties using CMOS compatible platform and phase-changed materials.
