“…However the deficiency was compensated by embedding the MLR in a silicone rubber which has lower and near to the refractive index of silica microfiber. The transmission spectrum with a frequency spectral range (FSR) of 30GHz is observed from the MLR (Caspar and Bachus, 1989 ). Later on, Sumetsky et al had demonstrated the fabrication of MLR from a ~1µm diameter waist microfiber which has the highest achieved loaded Qfactor as high as 120,000 (Sumetsky et al, 2006 ).…”

“…Caspar et al suggest embedding the microfiber resonator into a medium that has a slightly lower refractive index than that of silica. Due to the small index contrast, the microfiber has a larger evanescent field which yields stronger coupling in the resonator (Caspar and Bachus, 1989;. Besides being used as a post-fabrication remedy for improving the resonance condition of the resonator, embedding also offers good protection from the fast aging process and enabling portability for the microfiber devices.…”

“…The first loop resonator was demonstrated in 1989 by Caspar et al [131]. The effect of birefringence, the shape of resonances, and the free spectrum range that determines the spectral characteristics could be adjusted by the alignment of the input and output ends of the loop to vary the microfiber self-coupling, which were attached to each other through the Vander Waals and electrostatic forces [132].…”

Recent developments in fiber-optic sensing have involved booming research in the design and manufacturing of novel micro-structured optical fiber devices. From the conventional tapered fiber architectures to the novel micro-machined devices by advanced laser systems, thousands of micro-structured fiber-optic sensors have been proposed and fabricated for applications in measuring temperature, strain, refractive index (RI), electric current, displacement, bending, acceleration, force, rotation, acoustic, and magnetic field. The renowned and unparalleled merits of sensors-based micro-machined optical fibers including small footprint, light weight, immunity to electromagnetic interferences, durability to harsh environment, capability of remote control, and flexibility of directly embedding into the structured system have placed them in highly demand for practical use in diverse industries. With the rapid advancement in micro-technology, micro-structured fiber sensors have benefitted from the trends of possessing high performance, versatilities and spatial miniaturization. Here, we comprehensively review the recent progress in the micro-structured fiber-optic sensors with a variety of architectures regarding their fabrications, waveguide properties and sensing applications.

“…The first demonstration of a 2 mm diameter LR was carried out with an OMF having r~4.2μm [58]: since the OMF size was too large to ensure sufficient self coupling, the LR was embedded into a silicone-rubber. In free space, an OMF with r~500nm was used to demonstrate a LR with a Q-factor of 95000 [57].…”
