Demonstration of an All‐Optical AND Gate Mediated by Photochromic Molecules

Advanced Functional Materials, EarlyView.
A logic AND gate that runs on photons is demonstrated. It relies on two spatially separated photochromic molecules that work in tandem. Abstract The realization of a photonic logic AND gate, i.e. a logic AND gate that runs on photons rather than electrons, and where all steps are controlled by light, is demonstrated. In a proof‐of‐principle experiment,

Time-correlated photons from an In_{0.5}Ga_{0.5}P photonic crystal cavity on a silicon chip

Physical Review Research, 2022
Time-correlated photon pairs are generated by triply resonant four-wave-mixing in an In_{0.5}Ga_{0.5}P photonic crystal cavity. Maximal efficiency is reached by actively compensating for the residual spectral misalignment of the cavity modes.

Optomechanical coupling in photonic crystal supported nanomechanical waveguides

, 2009
We report enhanced optomechanical coupling by embedding a nano-mechanical beam resonator within an optical race-track resonator. Precise control of the mechanical resonator is achieved by clamping the beam between two low-loss photonic crystal waveguide ...

High index contrast photonic platforms for on-chip Raman spectroscopy [PDF]

, 2019
Nanophotonic waveguide enhanced Raman spectroscopy (NWERS) is a sensing technique that uses a highly confined waveguide mode to excite and collect the Raman scattered signal from molecules in close vicinity of the waveguide. The most important parameters
