Ultrafast, Confined Lights from Quantum Devices

Spatial and temporal distributions of lights have been engineered separately due to limited space-time bandwidth product of optical devices. By introducing multi-functional quantum materials, we expect simultaneous space-time control can be demonstrated for the device-level demonstration of space-time wavepackets and ultrafast structured lights.

Quantum-enhanced Magneto-optic Metrology

Magneto-optics offers highly accessible, remote, ultrafast magnetization measurement technology. The main drawback is the low sensitivity due to the small light-magnetism interaction. By introducing quantum twin beams, we expect the sensitivity of magneto-optic measurements can be enhanced beyond standard quantum limits. 

Topological Quasiparticles from Optical Resonances

Quasiparticles in condensed matter emerge from the various interactions between elementary particles. In optics, the lack of interaction between photons hinders the construction of those quasiparticles. By emulating topological interactions in photonic devices, we expect that optical resonances can spontaneously generate topological textures and singularities, such as optical vortices and optical skyrmions.
