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…
Diamond Mirrors for High-Power Lasers
H. Atikian, N. Sinclair, P. Latawiec +12
High-power lasers have numerous scientific and industrial applications. Some key areas include laser cutting and welding in manufacturing, directed energy in fusion reactors or def…
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…
An integrated diamond Raman laser pumped in the near-visible
Pawel Latawiec, Vivek Venkataraman, Amirhassan Shams-Ansari +2
Using a high-Q diamond microresonator (Q > 300,000) interfaced with high-power-handling directly-written doped-glass waveguides, we demonstrate a Raman laser in an integrated platf…
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…
Large-scale quantum-emitter arrays in atomically thin semiconductors
Carmen Palacios-Berraquero, Dhiren M. Kara, Alejandro R. -P. Montblanch +7
The flourishing field of two-dimensional (2D) nanophotonics has generated much excitement in the quantum technologies community after the identification of quantum emitters (QEs) i…
Faraday cage angled-etching of nanostructures in bulk dielectrics
Pawel Latawiec, Michael J. Burek, Young-Ik Sohn +1
For many emerging optoelectronic materials, heteroepitaxial growth techniques do not offer the same high material quality afforded by bulk, single-crystal growth. However, the need…
Waveguide-loaded silica fibers for coupling to high-index micro-resonators
Pawel Latawiec, Michael J. Burek, Vivek Venkataraman +1
Tapered silica fibers are often used to rapidly probe the optical properties of micro-resonators. However, their low refractive index precludes phase-matching when coupling to high…
On-Chip Diamond Raman Laser
Pawel Latawiec, Vivek Venkataraman, Michael J. Burek +3
Synthetic single-crystal diamond has recently emerged as a promising platform for Raman lasers at exotic wavelengths due to its giant Raman shift, large transparency window and exc…
