“…With enhancement of the modern instrument detection accuracy, the application of slow light greatly improves the measurement resolution. The utilization of slow light in strain, [10] index, [11] absolute rotation, [12] absorption, [13] and other parametric sensing has been reported. However, the two types of slow light appear to have different effects on some parameters such as absolute rotation and absorption.…”

& Generation methods of structural slow light and the recent optical fiber sensing applications are summarized in this paper. Five kinds of different structures for slow light are discussed: in fiber Bragg grating, fiber Fabry-Perot cavity, circled coupled resonator optical waveguides, photonic crystal waveguides, and microspheres. The corresponding applications for optical fiber sensors of the different slow light technologies are also introduced. Developments of structural slow light and the characteristics of the slow light sensing methods are analyzed, and improvement trends and potential applications in the fiber-sensing field are forecasted. It is concluded that the technology of structural slow light will increase in fiber sensing and other fields.

“…Two resonators are coupled to two curved waveguides ending in a 3 dB beam splitter from which the interference signal of the two counter-propagating optical beams is obtained. A slightly different configuration is proposed in [80] ( Figure 15(b)) where two nested ring resonators, having different radius, are coupled each other and the external one is coupled to a bus waveguide. Both gyro configurations are phase-sensitive.…”

Low-cost chip-scale optoelectronic gyroscopes having a resolution ≤ 10 • /h and a good reliability also in harsh environments could have a strong impact on the medium/high performance gyro market, which is currently dominated by well-established bulk optical angular velocity sensors. The R&D activity aiming at the demonstration of those miniaturized sensors is crucial for aerospace/defense industry, and thus it is attracting an increasing research effort and notably funds.In this paper the recent technological advances on the compact optoelectronic gyroscopes with low weight and high energy saving are reviewed. Attention is paid to both the so-called gyroscope-on-a-chip, which is a novel sensor, at the infantile stage, whose optical components are monolithically integrated on a single indium phosphide chip, and to a new ultra-high Q ring resonator for gyro applications with a configuration including a 1D photonic crystal in the resonant path. The emerging field of the gyros based on passive ring cavities, which have already shown performance comparable with that of optical fiber gyros, is also discussed.

“…Especially, recent researches have indicated that slow light has good potential applications in variable optical delay lines or optical buffers of highcapacity communication networks [1,2], optical pulse synchronization [3], ultrafast all-optical information processing, quantum computing [4], nonlinear optical devices [5], true-time delay (TTD) in a phased-array antenna (PAA) [6,7], optical gyroscope and sensing [8,9], and miniaturization of many spectroscopy systems due to the availability of a variable delay line. The study of slow light also furthers our understanding of the fundamental physics of light, and nonlinear optical effects enhanced by slow light develop a new area for nonlinear optics.…”

This paper experimentally investigated slow light effect in cascaded silicon-on-insulator (SOI) microring resonators. Double channel and single channel sidecoupled integrated spaced sequence of resonators (SCISSOR) devices were fabricated with electron beam lithography and dry etching technology. The delay performances of the SCISSOR devices were demonstrated using non-return-to-zero (NRZ) and return-to-zero (RZ) signals at different bit rates. Group delays and bandwidths of cascaded microrings are significantly enhanced compared with single microring.
