“…The comb array is guided in translation by a flexure mechanism. Nazir and Bellouard [13] proposed a laser-to-fibre coupling mechanism contained in a monolithic fused silica tunable flexure mechanism (sub-nm resolution positioning over a tens of micrometres range of motion). Nazir et al [14] also used their concept of stressors to load a micro-tensile tester to perform long static stress measurements under normal atmospheric conditions.…”

Fused silica glass is a material with outstanding mechanical, thermal and optical properties. Being a brittle material, it is challenging to shape. In the last decade, the manufacturing of monolithic flexible mechanisms in fused silica has evolved with the femtosecond-laser-assisted etching process. However, instrumenting those structures is demanding. To address this obstacle, this article proposes to inscribe a Bragg Grating sensor inside a flexure and interface it with an optical fibre to record the strain using a spectrum analyser. The strain sensitivity of this Bragg Grating sensor is characterized at 1.2 pm/μϵ (1 μϵ = 1 microstrain). Among other applications, deformation sensing can be used to record a force. Its use as a micro-force sensor is estimated. The sensor resolution is limited by our recording equipment to 30 μN over a measurement range above 10 mN. This technology can offer opportunities for surgery applications or others where precision and stability in harsh environments are required.

Fiber optic lasers have been designed with rare-earth-doped fibers because of their potential use in laser systems is inversely proportional to the length of the cavity. For remote sensing,a fiber laser having cavities with different lengths generates different attracted more attention because that wavelength coincides with that ofintermodal spacing frequencies. These frequencies can be measured the region of least loss for silica fibers. . c avity , which can have a Fabry-Perot or ring configuration. The most common elements to form cavities are reflecting mirrors and fiber Bragg gratings, these have a wide advantage over the former because they are robust in nature.with a radio frequency (RF) analyzer and the length of the cavity can be calculated
