Linear Laser Tuning Using a Pressure-Sensitive Microbubble Resonator
Ramgopal Madugani, Yong Yang, Vu H Le +2
The tunability of an optical cavity is an essential requirement for many areas of research. Here, we use the Pound-Drever-Hall technique to lock a laser to a whispering gallery mod…
Optical nanofibre integrated into an optical tweezers for particle manipulation, in situ fibre probing, and optical binding studies
Ivan Gusachenko, Viet Giang Truong, Mary C. Frawley +1
Precise control of particle positioning is desirable in many optical propulsion and sorting applications. Here, we develop an integrated platform for particle manipulation consisti…
Autler-Townes splitting via frequency upconversion at ultra-low power levels in cold Rb atoms using an optical nanofiber
Ravi Kumar, Vandna Gokhroo, Kieran Deasy +1
The tight confinement of the evanescent light field around the waist of an optical nanofiber makes it a suitable tool for studying nonlinear optics in atomic media. Here, we use an…
Dissipative phase solitons in semiconductor lasers
François Gustave, Lorenzo Columbo, Giovanna Tissoni +5
We experimentally demonstrate the existence of non dispersive solitary waves associated with a 2 phase rotation in a strongly multimode ring semiconductor laser with coherent fo…
Optomechanical Transduction and Characterization of a Silica Microsphere Pendulum via Evanescent Light
Ramgopal Madugani, Yong Yang, Jonathan M Ward +2
Dissipative optomechanics has some advantages in cooling compared to the conventional dispersion dominated systems. Here, we study the optical response of a cantilever-like, silica…
