Atomic-scale sidewalls roughness smoothening thanks to high temperature hydrogen annealing is a key enabler for a low-loss (<0.5 dB/cm) silicon Q-photonics platform. Using this technology, authors report here about high-Q (Q1 >4 × 105) silicon micro-resonators for on-chip heralded single-photon bright quantum sources by spontaneous four-wave mixing.

Abstract
Atomic-scale sidewalls roughness smoothening thanks to high temperature hydrogen annealing is a key enabler for a low-loss (<0.5 dB/cm) silicon Q-photonics platform. Using this technology, authors report here about high-Q (Q1 >4 × 105) silicon micro-resonators for on-chip heralded single-photon bright quantum sources by spontaneous four-wave mixing.File in questo prodotto:
