Microfabrication of Soft Millirobots Propelled by Low Voltage Electrohydraulic Actuators
Advanced Materials Technologies, EarlyView.Manual layer‐by‐layer assembly is replaced by wafer‐level MEMS batch fabrication for compliant polymer‐based electrohydraulic actuators. The microfabricated devices integrate sacrificially defined microcavities, Parylene‐C‐sealed inlets, and multilayer polymer–metal films.

Strong Coupling in all‐Polymer Planar Microcavities
Advanced Optical Materials, EarlyView.Strong Coupling has been achieved in an all‐polymer microcavity with dielectric contrast Δn = 0.33 doped with TDBC. A Rabi splitting of 39 meV has been measured opening novel perspectives for polymer photonics. ABSTRACT In this work, strong coupling effect is observed in all‐polymer planar microcavities incorporating TDBC J‐aggregates dispersed into ...

Fiber optic sensing of liquid refractive index
Sensors and Actuators B: Chemical, 2007An optical fiber, partially stripped of its cladding is shown to sense refractive index of a liquid in which the uncladded sensing region is immersed, to a high degree of precision and over a wide range of refractive index. The slope of sensor response is found to be non linear, can have either sign and can change sign at around refractive index of the

Refractive index sensor for sensing high refractive index bioliquids at the THz frequency
Journal of the Optical Society of America B, 2021In this paper, a highly sensitive and low loss refractive index (RI) biosensor for high RI bio-analytes detection, such as for cholesterol, nicotine, and bacillus bacteria, is proposed. A novel, to the best of our knowledge, decagonal structure with porous core photonic crystal fiber (PC-PCF) is introduced.

Refractive index sensing and switching of leaky states in a metasurface
Optics Letters, 2021We theoretically propose leaky states in an electro-optic (EO)-based all-dielectric metasurface. The EO substrate tunes leaky modes to the desired wave band with changes in applied voltage ( V a p p ).

Twisted Optical Microfibers for Refractive Index Sensing
IEEE Photonics Technology Letters, 2011A simple, compact, and robust refractive index sensor is developed, by twisting a pair of silica microfibers to form a coupling device. The transmission spectrum of the device is highly sensitive to the surrounding refractive index and the highest sensitivity obtained is -2377 nm/refractive index unit (RIU), at the refractive index value of - 1.3680 ...

Hybrid Metal-Dielectric Metasurfaces for Refractive Index Sensing
Nano Letters, 2020Hybrid metal-dielectric nanostructures have recently gained prominence because they combine strong field enhancement of plasmonic metals and the several low-loss radiation channels of dielectric resonators, which are qualities pertaining to the best of both worlds.

Sensing the refractive index gradient of the atmosphere
SPIE Proceedings, 2006The refractive index gradient, averaged over short horizontal paths, in the atmosphere was experimentally investigated by using a method we developed, based on the use of thin parallel laser beams. Horizontal and vertical components of the gradient were shown to be directly related to the corresponding lateral displacements of the beams at the end of ...

S-Fiber Probe for Refraction Index Sensing
2017A refractive index (RI) sensor which based on an S-tapered fiber probe (STFP) with a silver mirror on its end facet is demonstrated. The fiber probe has a compact size of about 1 mm, making it proper for sensing in narrow or limited space. It is stiff to bend due to the short probe structure, leading to avoid the cross-sensitivity of bending.
