Towards applications: ultra-low-loss on-chip zero-index materials

Dirac-cone materials behave like an isotropic and impedance-matched zero-index medium at Dirac-point wavelength, enabling light-matter interactions in a spatially uniform optical mode with arbitrary shapes. However, such interactions are limited to small areas because of the propagation loss. We designed an ultra-low-loss and homogeneous zero-index material by introducing resonance-trapped bound Read More…

Introducing our latest work “Design of on-chip mid-IR frequency comb with ultra-low power pump in near-IR”

We theoretically demonstrated two novel designs of on-chip mid-infrared frequency comb. We believe that the combination of PPLN and electro-optic modulation based on LNOI integrated photonics platform can significantly increase the comb generation efficiency. Our theoretical results predict that a broadband mid-infrared frequency comb around 4.3 μm with nanowatt-power-level comb teeth can be proRead More…
