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 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
