Ultrabroadband Nonlinear Optics in Nanophotonic Periodically Poled Lithium Niobate Waveguides
Marc Jankowski, Carsten Langrock, Boris Desiatov +6
Quasi-phasematched interactions in waveguides with quadratic nonlinearities enable highly efficient nonlinear frequency conversion. In this article, we demonstrate the first genera…
High-dimensional frequency crystals and quantum walks in electro-optic microcombs
Christian Reimer, Yaowen Hu, Amirhassan Shams-Ansari +2
Synthetic optical structures have enabled studies of various physical processes and discoveries of new phenomena in a controllable manner. Past realizations, using for example coup…
Raman lasing and soliton modelocking in lithium-niobate microresonators
Mengjie Yu, Yoshitomo Okawachi, Rebecca Cheng +4
The recent advancement in lithium niobate on insulator (LNOI) technology is revolutionizing the optoelectronic industry as devices of higher performance, lower power consumption, a…
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…
Coherent two-octave-spanning supercontinuum generation in lithium-niobate waveguides
Mengjie Yu, Boris Desiatov, Yoshitomo Okawachi +2
We demonstrate coherent supercontinuum generation (SCG) in a monolithically integrated lithium-niobate waveguide, under the presence of second- and third-order nonlinear effects. W…
