Forward Brillouin scattering fiber sensors can detect and analyze media outside the cladding of standard fibers, where guided light does not reach. Nearly all such sensors reported to-date have relied on the radially symmetric guided acoustic modes o

Optical fibers are an excellent sensor platform. However, the detection and analysis of media outside the cladding and coating of standard fibers represent a long-standing challenge: light that is guided in the single optical core mode does not reach

Highly-coherent and narrow linewidth fibre lasers are determinant in several sensing techniques. Here the authors develop a laser based on forward Brillouin scattering achieving ultra high coherence in single-, few- and multi-mode operation regimes.

Abstract Opto-mechanical interactions in guided wave media are drawing great interest in fundamental research and applications. Forward stimulated Brillouin scattering, in particular, is widely investigated in optical fibres and photonic integrated c

Exceptional points enable exotic optical responses, but they usually require complex devices. Here, the authors realise an anti-PT symmetric response supporting exceptional points through Brillouin interactions in a standard optical fibre, which can

The authors implement surface acoustic waves on the silicon photonics platform by exciting a metallic grating with modulated pump light to enable microwave-photonic devices without the need for piezo-electric actuation, complex suspensions or hybrid

Distributed fibre sensors are so far restricted to the monitoring of conditions within the core. Here, Bashan et al. introduce distributed optomechanical mapping of outside media, where light cannot reach. The sensor resolves forward stimulated Brill

The analysis of surrounding media has been a long-standing challenge of optical fiber sensors. Measurements are difficult due to the confinement of light to the inner core of standard fibers. Over the last two years, new sensor concepts have enabled

Forward stimulated Brillouin scattering (F-SBS) is a third-order nonlinear-optical mechanism that couples between two co-propagating optical fields and a guided acoustic mode in a common medium. F-SBS gives rise to nonlinear wave mixing along optic

An opto-electronic radio-frequency oscillator that is based on forward scattering by the guided acoustic modes of a standard single-mode optical fiber is proposed and demonstrated. An optical pump wave is used to stimulate narrowband, resonant guided
