Integrated Si3N4 Soliton Microcomb Driven by a Compact Ultra-low-noise Laser

Tobias Kippenberg, Rui Ning Wang, Nicolas Volet, Junqiu Liu, Erwan Guillaume Albert Lucas, Arslan Sajid Raja, Jijun He

We generate 100-GHz soliton microcombs in a photonic integrated high-Q Si3N4 microresonator using an ultra-compact, high-power and low-frequency-noise semiconductor-based laser. The soliton is initiated via direct current tuning of the laser. (C) 2019 The ...

IEEE2019

Diamond is an exceptional material - hard, stiff, transparent, which makes it ideal for the fabrication of optical and mechanical systems that take advantage of these properties. Diamond is not only "better", but it offers the possibility of integrating br ...
