Thermal noise and optomechanical features in the emission of a membrane-coupled compound cavity laser diode [PDF]

, 2016
We demonstrate the use of a compound optical cavity as linear displacement detector, by measuring the thermal motion of a silicon nitride suspended membrane acting as the external mirror of a near-infrared Littrow laser diode.

Multiphysics Coupling for PB-FHRs

, 2020
Pebble-bed fuelled, molten salt-cooled nuclear reactors (PB-FHRs) involve interactions between a fluid coolant phase, solid particle fuel phase and neutron interactions enabling fission of nuclear fuel for heat production. As these three aspects are highly interdependent, this work presents a three-way coupled methodology for simulation of PB-FHRs to ...

Tunable nonlinear graphene metasurfaces

, 2015
We introduce the concept of nonlinear graphene metasurfaces employing the controllable interaction between a graphene layer and a planar metamaterial. Such hybrid metasurfaces support two types of subradiant resonant modes, asymmetric modes of structured

Electrically Tunable On‐Chip Topological Photonics with Integrated Carbon Nanotubes

Advanced Functional Materials, EarlyView.
This work demonstrates electrically tunable on‐chip topological THz devices by integrating 2D carbon nanotube (CNT) sheets with valley‐Hall photonic crystals, enabling broadband transmission modulation (71% modulation depth) and tunable narrowband filtering (0.54 GHz shift) through electrically induced thermal tuning. This advancement paves the way for
