On-Chip Erbium-Doped Tantalum Oxide Microring Hybrid Cavity Single-Mode Laser
Like Shui, Ruixuan Yi, Chenyang Zhao +4
We demonstrate a high-performance, single-mode Er:Ta2O5 microring laser monolithically integrated on a silicon platform via a customized Damascene process. The Er:Ta2O5 gain medium…
On-chip quadratically nonlinear photodetector
Yu Zhang, Xiaoqing Chen, Mingwen Zhang +5
Involving deterministically nonlinear photoresponse in on-chip photodetector is intriguing to develop sophisticated functions in photonic integrated circuits, such as in-sensor com…
Microcavity induced by few-layer GaSe crystal on silicon photonic crystal waveguide for efficient optical frequency conversion
Xiaoqing Chen, Yanyan Zhang, Yingke Ji +8
We demonstrate the post-induction of high-quality microcavity on silicon photonic crystal (PC) waveguide by integrating few-layer GaSe crystal, which promises highly efficient on-c…
Cylindrical vector resonant modes achieved in planar photonic crystal cavities with enlarged air-holes
Kang Chang, Liang Fang, Chenyang Zhao +2
We reveal a triangular-lattice planar photonic crystal supports Bloch modes with radially and azimuthally symmetric electric field distributions at the top band-edge of the first p…
Microwatts continuous-wave pumped second harmonic generation in few- and mono-layer GaSe
Xuetao Gan, Chenyang Zhao, Siqi Hu +6
We demonstrate the first achievement of continuous-wave (CW) pumped second harmonic generation (SHG) in few- and mono-layer gallium selenide (GaSe) flakes, which are coated on sili…
High performance graphene oxide-based humidity sensor integrated on a photonic crystal cavity
Xuetao Gan, Chenyang Zhao, Qingchen Yuan +5
We report a high performance relative humidity (RH) microsensor by coating a few-layer graphene oxide (GO) flake over a photonic crystal (PC) cavity. Since the GO layer has a high…
Generation of vector beams in planar photonic crystal cavities with multiple missing-hole defects
Chenyang Zhao, Xuetao Gan, Sheng Liu +2
We propose a novel method to generate vector beams in planar photonic crystal cavities with multiple missing-hole defects. Simulating the resonant modes in the cavities, we observe…
