“…Nowadays, the near-field optics methods, which make use of evanescent waves that exists in the subwavelength region near the interface of two medias, have attracted more and more interests. Inspired by the recent rapid progress of nanotechnology, different near-field mechanisms have been incorporated into the RI measurement, notably surface plasmon resonance ͑SPR͒, [19][20][21] whispering gallery modes of microresonators, 22 photonic bandgap waveguides, 23 photonic crystal fibers, 24 and local coupling of slab waveguides and tapered optical fibers. 25,26 As the near-field effect is confined to a subwavelength region, it intensifies the interaction and thus further improves the sensitivity to a level close to 10 −7 RIU.…”

This paper presents the design and analysis of a liquid refractive index sensor that utilizes a unique physical mechanism of resonant optical tunneling effect ͑ROTE͒. The sensor consists of two hemicylindrical prisms, two air gaps, and a microfluidic channel. All parts can be microfabricated using an optical resin NOA81. Theoretical study shows that this ROTE sensor has extremely sharp transmission peak and achieves a sensitivity of 760 nm/refractive index unit ͑RIU͒ and a detectivity of 85 000 RIU −1 . Although the sensitivity is smaller than that of a typical surface plasmon resonance ͑SPR͒ sensor ͑3200 nm/RIU͒ and is comparable to a 95% reflectivity Fabry-Pérot ͑FP͒ etalon ͑440 nm/RIU͒, the detectivity is 17 000 times larger than that of the SPR sensor and 85 times larger than that of the FP etalon. Such ROTE sensor could potentially achieve an ultrahigh sensitivity of 10 −9 RIU, two orders higher than the best results of current methods.

Abstract:The ability to engineer and shape the phase profile of optical beams is in the heart of any optical element. Be it a simple lens or a sophisticated holographic element, the functionality of such components is dictated by their spatial phase response. In contrast to conventional optical components which rely on thickness variation to induce a phase profile, metasurfaces facilitate the realization of arbitrary phase distributions using large arrays with subwavelength and ultrathin (tens of nanometers) features. Such components can be easily realized using a single lithographic step and is highly suited for patterning a variety of substrates, including nonplanar and soft surfaces. In this article, we review the recent developments, potential, and opportunities of metasurfaces applications. We focus primarily on flat optical devices, holography, and beam-shaping applications as these are the key ingredients needed for the development of a new generation of optical devices which could find widespread applications in photonics.

“…Optical fibers have been successful as optical sensing devices due to the combination of their small size, flexibility, low cost, and ability to measure in difficult to reach areas [1]. For the most part, optical fibers are used to deliver light to an area of interest and to collect the signal created locally as a result of the transduction mechanism.…”

Abstract: Microstructured optical fibers, particularly those with a suspended-core geometry, have frequently been argued as efficient evanescent-field fluorescence-based sensors. However, to date there has not been a systematic comparison between such fibers and the more common geometry of a multi-mode fiber tip sensor. In this paper we make a direct comparison between these two fiber sensor geometries both theoretically and experimentally.Our results confirm that suspended-core fibers provide a significant advantage in terms of total collected fluorescence signal compared to multi-mode fibers using an equivalent experimental configuration.
