Reconfigurability of photonic integrated circuits (PICs) has become increasingly important due to the growing demands for electronic–photonic systems on a chip driven by emerging applications, including neuromorphic computing, quantum information, and microwave photonics. Success in these fields usually requires highly scalable photonic switching units as essential building blocks. Current photonic...
We propose an on-chip self-electro-optic bistable device based on hybrid silicon microring resonators. The device enables bistability at low optical power with the switching energy of only ∼5 fJ and can potentially operate at ∼100 GHz.
We demonstrate a novel light source, based on a photonic crystal cavity integrated van der Waals light emitting diode, which can be operated at room temperature with fast modulation speed.
We demonstrate a silicon photonic crystal cavity enhanced second-harmonic generation (SHG) in tungsten diselenide. The observed SHG is enhanced by a factor of ∼200 compared to a bare monolayer on silicon.
Monolayer materials present a new opportunity in integrated photonics, due to their unprecedented ability to be integrated on any substrate, and exceptional optoelectronic properties. Here, we present our recent results on laser and nonlinear optical devices based on monolayer materials integrated on nanophotonic devices.
