Abstract The quantum noise of light, attributed to the random arrival time of photons from a coherent light source, fundamentally limits optical phase sensors. An engineered source of squeezed states suppresses this noise and allows phase detection s

Abstract Graphene together with other 2D nanomaterials, due to their exceptional physiochemical properties, are often considered as excellent building blocks for fabrication of more complex heterostructures. Despite the processing‐related issues th

Thin-film lithium niobate (TFLN) is an emerging platform for compact, low-power nonlinear-optical devices, and has been used extensively for near-infrared frequency conversion. Recent work has extended these devices to mid-infrared wavelengths, where

We demonstrate second harmonic generation of blue light on an integrated thin-film lithium niobate waveguide and observe a conversion efficiency of $\eta_0= 33000\%/\text{W-cm}^2$, significantly exceeding previous demonstrations.
