Raman Laser Switching Induced by Cascaded Light Scattering
Sho Kasumie, Fuchuan Lei, Jonathan M Ward +3
We show that, in multimode Raman lasers, cascaded light scattering (CLS) not only extends the optical frequency range, but could also modulate the laser dynamics. The origin of thi…
Tunable erbium-doped microbubble laser fabricated by sol-gel coating
Yong Yang, Fuchuan Lei, Sho Kasumie +4
In this work, we show that the application of a sol-gel coating renders a microbubble whispering gallery resonator into an active device. During the fabrication of the resonator, a…
Cavity ring-up spectroscopy for dissipative and dispersive sensing in a whispering gallery mode resonator
Yong Yang, Ramgopal Madugani, Sho Kasumie +2
In whispering gallery mode resonator sensing applications, the conventional way to detect a change in the parameter to be measured is by observing the steady state transmission spe…
Four-wave mixing parametric oscillation and frequency comb generation at visible wavelengths in a silica microbubble resonator
Yong Yang, Xuefeng Jiang, Sho Kasumie +5
Frequency comb generation in microresonators at visible wavelengths has found applications in a variety of areas such as metrology, sensing, and imaging. To achieve Kerr combs base…
Adiabatic excitation of a confined particle in one dimension with a variable infinitely sharp wall
Sho Kasumie, Manabu Miyamoto, Atushi Tanaka
It is shown that adiabatic cycles excite a quantum particle, which is confined in a one-dimensional region and is initially in an eigenstate. During the cycle, an infinitely sharp…
