Exploring light at the nanoscale

Research

Light–matter interaction across scales.

From sub-wavelength photonic crystals to atomically thin two-dimensional semiconductors, our work spans seven interconnected thrusts.

Sub-wavelength nanophotonic structures, plasmonic resonators, and integrated photonic circuits.

Two-dimensional semiconductors and quantum-confined materials for photonic applications.

Electrically driven nanowire and microdisk light sources, micro-LEDs, and photodetectors.

In-house process line: SEM, photolithography, RIE, e-beam evaporator, critical-point dryer.

Visible and near-infrared optical setups, butt-coupling with lensed fibers.

Cluster-node FDTD/FEM simulation of nanophotonic devices.

Ultra-clean sample prep, exfoliation, and pre-fabrication processing.
