- Nonlinear nanophotonics circuits: building blocks for optical frequency synthesis, filtering and signal processing, AP.JP2
Abstract
The recent development of active and passive photonic components has revolutionized spectroscopy techniques, compact sources of light of high coherence, data transmission and even redefined the optical computing paradigm. In this proposal we aim to explore the collective and multimodal behavior that appears in optical microcavities as a consequence of nonlinear effects of electronic and...

- Nanophotonics in Group IV and III-V semiconductors, AP.JP
Abstract
The advancement of the nanophotonics research in the past decade have shown its potential to establish disruptive technology in the fields of telecom, multi-core processors and radio-frequency signal proces- sing. In this project we propose the development of on-chip nanophotonic devices based on silicon and III-V materials. Our focus will be two-fold, the coupling between mechanical an...
- On-chip degenerate parametric amplification for photonic information processing, BP.DR
Abstract
Degenerate parametric amplification is a nonlinear process that generates two photons of same frequency in a binary phase state (either 0 or pi with respect to the pump laser). In this project, we take advantage of this property to simulate spin states and find the ground state of an Ising Hamiltonian. This Ising machine is to be implemented in on-chip optical platforms and could potent...
- Synchronism of optomechanical oscillators, BP.IC
Abstract
In this project we aim to explore the interactions between optomechanical oscillators, analyzing, mainly, the possibility of synchronizing mechanical modes of these oscillators through the optical coupling. (AU)
- Frequency comb generation in optical microcavities, BP.MS
Abstract
Optical microcavities combine high quality factors and small modal areas to enhance the intensity of intracavity light, which enables the exploration of nonlinear optical phenomena. In this master's thesis, we study frequency comb generation in silica microdisks through four wave mixing, a third order nonlinear effect. Several applications follow from this absolute frequency reference, ...
- Introduction to microfabrication techniques, BP.IC
Abstract
The fabrication of microstructures consists in transfering a lithography pattern to a substrate, by means of optical masks or electron beam.In this project the candidate will become familiar with electron lithography techniques in order to fabricate optical microcavities. We will also characterize these microcavities experimentally using techniques already mastered by the student.
