Numerical Simulation of Noise in Pulsed Brillouin Scattering
Oscar A. Nieves, Matthew D. Arnold, Michael J. Steel +2
We present a numerical method for modelling noise in Stimulated Brillouin Scattering (SBS). The model applies to dynamic cases such as optical pulses, and accounts for both thermal…
Picosecond acoustic dynamics in stimulated Brillouin scattering
Johannes Piotrowski, Mikołaj K. Schmidt, Birgit Stiller +2
Recent experiments demonstrating storage of optical pulses in acoustic phonons based on stimulated Brillouin scattering raise a number of questions about the spectral and temporal…
Noise and Pulse Dynamics in Backward Stimulated Brillouin Scattering
Oscar A. Nieves, Matthew D. Arnold, M. J. Steel +2
We theoretically and numerically study the effects of thermal noise on pulses in backwards Stimulated Brillouin Scattering (SBS). Using a combination of stochastic calculus and num…
ARRAW: Anti-resonant reflecting acoustic waveguides
Mikołaj K. Schmidt, Matthew C. O'Brien, Michael J. Steel +1
Development of acoustic and optoacoustic on-chip technologies calls for new solutions to guiding, storing and interfacing acoustic and optical waves in integrated silicon-on-insula…
Quantum description of surface-enhanced resonant Raman scattering within a hybrid-optomechanical model
Tomáš Neuman, Ruben Esteban, Geza Giedke +2
Surface-Enhanced Raman Scattering (SERS) allows for detection and identification of molecular vibrational fingerprints in minute sample quantities. The SERS process can be also exp…
Suspended mid-infrared waveguides for Stimulated Brillouin Scattering
Mikołaj K. Schmidt, Christopher G. Poulton, Goran Z. Mashanovich +3
We theoretically investigate a new class of silicon waveguides for achieving Stimulated Brillouin Scattering (SBS) in the mid-infrared (MIR). The waveguide consists of a rectangula…
