We investigate both theoretically and experimentally a laser-based controlled tuning of the nonlinear behaviors of a single mechanical resonator. Thanks to localized three-dimensional modifications induced by femtosecond-laser irradiation, a Duffing-like o ...
We propose a device architecture capable of direct quantum coherent electro-optical conversion of microwave-to-optical photons. The hybrid system consists of a planar superconducting microwave circuit coupled to an integrated whispering-gallery-mode micror ...
This project addresses the design, construction and evaluation of a peeling hook with force measurement capability for in-vivo intra-ocular vitreoretinal surgery. The force sensor consists of a miniature multi-degree-offreedom flexure where deformations in ...
One of the most essential building blocks in modem electronics is the flip-flop. A flip-flop operates bi-stably between two states, remaining at a given output level (high or low level) until a specific input control signal changes. For many years, photoni ...
During this project we studied cavities as an alternative method to stripline resonators, to create an oscillating magnetic field. We were able to simulate different cavity designs and reproduce theoretical results as a numerical simulation and experimenta ...
Many countries rely on high levels of generation from Variable Renewable Energies (VREs) to decarbonise their power systems. However, scaling up VREs beyond a certain threshold generates new challenges in the already complex electricity system and renewabl ...
We demonstrate diamond optomechanical crystals (OMCs), which support a similar to 6 GHz mechanical cavity coupled to a co-resonant similar to 200 THz photon field. Diamond OMCs are optically driven to a cooperativity >1, highlighted by observed 'phonon las ...
Organic salt crystals, e.g. DAST, OH1, and DSTMS, pumped by ultra-short infrared laser are efficient THz emitters. We review our latest results on the generation in organic crystals of THz single-cycle transients with field strength of 1.5 MV/cm. The energ ...
In a linear slow light system the delaying process is necessarily inducing distortion for fundamental reasons, strictly bounding the maximum delay-bandwidth product to unity. Slowing the light does not directly enhance light-matter interaction, but is a co ...
The Time Of internally Reflected Cherenkov light (TORCH) detector is under development. Charged particle tracks passing through a 1 cm plate of quartz will generate the Cherenkov photons, and their arrival will be timed by an array of micro-channel plate p ...
