Spontaneous parametric down-conversion (SPDC) has become a key method for generating entangled photon pairs. Periodically poled thin-film lithium niobate (TFLN) waveguides induce strong SPDC but require complex fabrication processes. In this work, we

Abstract High‐performance continuous‐wave (CW) vertical‐cavity surface‐emitting lasers (VCSELs) rely on efficient thermal management for which top‐emitting 930 nm thin‐film VCSELs are integrated with a copper‐plated heatsink by using a

As a perfect graphene absorber without any external mirrors, we proposed asymmetric slot-assisted grating structures supporting two degenerate resonant modes of the guided-mode resonances (GMR) and the quasi-bound states in the continuum (quasi-BIC).
