“…This detection approach is particularly suited for monitoring the kinetics of transient processes without interfering with the reactions. Various monolithic optical devices for refractive index sensing have been proposed [94]; standard approaches, based on integrated optics, include Mach-Zehnder Interferometers (MZIs) [95], Young interferometers [96], and Bragg gratings [97]. These devices are fabricated by various techniques such as plasma vapour deposition, reactive ion etching, and also liquid-core waveguides [98].…”

This paper provides an overview of the rather new field concerning the applications of femtosecond laser microstructuring of glass to optofluidics. Femtosecond lasers have recently emerged as a powerful microfabrication tool due to their unique characteristics. On the one hand, they enable to induce a permanent refractive index increase, in a micrometer-sized volume of the material, allowing single-step, three-dimensional fabrication of optical waveguides. On the other hand, femtosecond-laser irradiation of fused silica followed by chemical etching enables the manufacturing of directly buried microfluidic channels. This opens the intriguing possibility of using a single laser system for the fabrication and three-dimensional integration of optofluidic devices. This paper will review the state of the art of femtosecond laser fabrication of optical waveguides and microfluidic channels, as well as their integration for high sensitivity detection of biomolecules and for cell manipulation.

“…These structural devices show significant improvement of refractive index sensitivity over the conventional strip waveguide based ring resonator, demonstrated by K. D. Vos et al [6]. Integration of Bragg gratings on SOI platform with promising application in bio and chemical sensing has also been reported [7], [8]. The conventional strip and rib waveguide based Bragg gratings use the evanescent field tails for the sensing, thus exhibiting a lower sensitivity with high quality (Q) factor.…”

“…The development of miniature and label-free optical sensors is very critical for applications in a wide range of areas such as medicine, environment, forensic and food quality control. As a result, there have been several reports on different types of optical transduction and sensing mechanisms such as surface plasmon resonance [1,2], refractive index change [3,4,5] and Raman scattering [6,7]. Nevertheless, the Bragggrating structures in a planar format are more easily integrated with other photonic sub-components and could be potentially more sensitive.…”

The applications of Bragg-grating concepts in a multitude of photonic device functionalities are well established, in particular, in the design of planar and chip-based miniature device components for dense photonic integrated circuits. In many situations, the Bragg-grating structures are designed to function as a broad or narrow band-pass filter, as a multichannel coupled defects filter, an optical waveguide and an optical sensor. In this work, Bragg-grating concepts are applied in several different scenarios with applications ranging from Bragg-grating optical microcavity filter, Bragggrating optical waveguide and a Bragg-slot waveguide. The Bragg-grating structures integrated with slot waveguide are shown to be very promising candidates for label-free optical sensing applications with sensitivity as high as 500nm/RIU. This work demonstrates the versatility of Bragg-grating structures for multiple device functionalities through design for a wide range of devices applications in several scientific and technological areas.
