Reliable micro-transfer printing method for heterogeneous integration of lithium niobate and semiconductor thin films
Tom Vandekerckhove, Tom Vanackere, Jasper De Witte +6
High-speed Pockels modulation and second-order nonlinearities are key components in optical systems, but CMOS-compatible platforms like silicon and silicon nitride lack these capab…
Resource efficient single photon source based on active frequency multiplexing
Serge Massar, Stephane Clemmen
We propose a new single photon source based on the principle of active multiplexing of heralded single photons which, unlike previously reported architecture, requires a limited am…
