Brillouin scattering induced transparency and generation of slow and fast light
… analogue of EIT is demonstrated using the two optical modes that are coupled through a phase matched acoustic mode. The coherent coupling of two energy levels is emulated by the acousto-optic interaction of Brillouin scattering. The probe phase response is analyzed to estimate BSIT's effect on …

Suppression of disorder-induced scattering in optomechanical systems
High-Q optical and mechanical resonators have been utilized in ultra-high precision metrology, transducers, sensor applications, and even investigating quantum mechanics at mesoscales. However, these low-loss devices are often limited by sub-wavelength fluctuations within the host material, that …
