In early 2017, I moved to Sydney to join researchers from groups of Prof. Mike Steel, Prof. Chris Poulton and Prof. Ben Eggleton – experts in nonlinear integrated optics – and work on designing new structures for stimulated Brillouin scattering. Here are my first contributions to that field:
Several papers on the classical modelling of noise in Brillouin waveguides (see blog post):
“Noise in Brillouin based information storage“, Oscar A. Nieves, Matthew D. Arnold, Mikołaj K. Schmidt, M. J. Steel, Christopher G. Poulton, Optics Express 29, 39486-39497 (2021). https://arxiv.org/abs/2108.02945
“Numerical simulation of noise in pulsed Brillouin scattering”, Oscar A. Nieves, Matthew D. Arnold, M. J. Steel, Mikołaj K. Schmidt, Christopher G. Poulton, Journal of the Optical Society of America B 38 (8), 2343-2352 (2021). https://arxiv.org/abs/2106.12185
- “Noise and pulse dynamics in backward stimulated Brillouin scattering”, Oscar A. Nieves, Matthew D. Arnold, M. J. Steel, Mikołaj K. Schmidt, Christopher G. Poulton, Optics Express 29, 3132-3146 (2021). (open access) https://arxiv.org/abs/2011.08338.
“Picosecond acoustic dynamics in stimulated Brillouin scattering”, Johannes Piotrowski, Mikołaj K. Schmidt, Birgit Stiller, Christopher G. Poulton, Michael J. Steel, Optics Letters 46, 2972-2975 (2021). https://arxiv.org/abs/2103.05732 (see blog post)
“ARRAW: anti-resonant reflecting acoustic waveguides,” Mikołaj K. Schmidt, Matthew C. O’Brien, Michael J. Steel, Christopher G. Poulton, New Journal of Physics 22, 053011 (2020). arXiv:1909.01632.
we look to we introduce a new type of optoacoustic waveguides, dubbed ARRAWs (Anti‑Resonant Reflecting Acoustic Waveguides), which implement acoustic guidance in multi-layer waveguides planar and cylindrical by engineering anti-reflective cladding layers that suppress the dissipation of acoustic waves (see blog entry)
“Suspended mid-infrared waveguides for Stimulated Brillouin Scattering”, Mikołaj K. Schmidt, Christopher G. Poulton, Goran Z. Mashanovich, Graham T. Reed, Benjamin J. Eggleton, M.J. Steel, arXiv:1811.02749 (2018).
here we design a Si waveguide suspended in air by ribs, which are structured into a 1D phononic crystal with a stopband tuned to the fundamental vibrational mode of the waveguide, mediating forward Brillouin scattering
