Confinement of long-lived interlayer excitons in WS/WSe heterostructures
Alejandro R. -P. Montblanch, Dhiren M. Kara, Ioannis Paradisanos +13
Interlayer excitons in layered materials constitute a novel platform to study many-body phenomena arising from long-range interactions between quantum particles. The ability to loc…

Supercontinuum generation in angle-etched diamond waveguides
Amirhassan Shams-Ansari, Pawel Latawiec, Yoshitomo Okawachi +8
We experimentally demonstrate on-chip supercontinuum generation in the visible region in angle etched diamond waveguides. We measure an output spectrum spanning 670 nm to 920 nm in…

Competition between Raman and Kerr effects in microresonator comb generation
Yoshitomo Okawachi, Mengjie Yu, Vivek Venkataraman +5
We investigate the effects of Raman and Kerr gain in crystalline microresonators and determine the conditions required to generate modelocked frequency combs. We show theoretically…
