Non-contact and label-free biomechanical imaging: Stimulated Brillouin microscopy and beyond

open access: yesFrontiers in Physics, 2023
Brillouin microscopy based on spontaneous Brillouin scattering has emerged as a unique elastography technique because of its merit of non-contact, label-free, and high-resolution mechanical imaging of biological cell and tissue.

Cascaded forward Brillouin lasing in a chalcogenide whispering gallery mode microresonator

open access: yesAPL Photonics, 2022
We report the first observation of cascaded forward stimulated Brillouin scattering in a microresonator platform. We have demonstrated 25 orders of intramodal Stokes beams separated by a Brillouin shift of 34.5 MHz at a sub-milliwatt threshold at 1550 nm.

New approaches to extending the performance of Brillouin based slow light systems [PDF]

open access: yes, 2007
We review the development of several new approaches for extending the performance of Brillouin based slow light systems. In particular we describe the use of cavity effects to enhance the achievable delays, gain saturation to decouple the delay and ...

Stimulated Brillouin scattering threshold in double-clad fibers with various cladding shapes [PDF]

open access: yes, 2009
We present a detailed numerical investigation about the stimulated Brillouin scattering (SBS) threshold power of double-clad optical fibers having different inner-cladding shapes. Generally, fibers with broken symmetry inner-cladding are usually employed

Fiber-Based Techniques to Suppress Stimulated Brillouin Scattering

open access: yesPhotonics, 2023
Stimulated Brillouin scattering (SBS) is the major factor that limits the maximum optical fiber output power in narrow linewidth applications, which include important fields such as passive optical networks (PONs), high-power fiber amplifiers, and lasers.
