Microelectromechanical systems bimaterial terahertz sensor with integrated metamaterial absorber.
This Letter describes the fabrication of a microelectromechanical systems (MEMS) bimaterial terahertz (THz) sensor operating at 3.8 THz. The incident THz radiation is absorbed by a metamaterial structure integrated with the bimaterial. The absorber was designed with a resonant frequency matching the quantum cascade laser illumination source while simultaneously providing structural support, des...
متن کاملA Label-free Protein Sensor Based on Mems Fabry-perot Interferometer Integrated with Silicon Photodiode
ABSTRACT We have newly developed a label-free protein sensor based on MEMS Fabry-Perot interferometer integrated with a photodiode, which utilizes nonlinear optical effect of the Fabry-Perot resonance to enhance the sensitivity of surface stress. A parylene was used for a deformable membrane of the protein sensor because of the high optical transmittance and low Young’s modulus. Theoretical sig...
متن کاملOptical Fiber Temperature and Torsion Sensor Based on Lyot-Sagnac Interferometer
An optical fiber temperature and torsion sensor has been proposed by employing the Lyot-Sagnac interferometer, which was composed by inserting two sections of high-birefringence (HiBi) fiber into the Sagnac loop. The two inserted sections of HiBi fiber have different functions; while one section acts as the temperature sensitive region, the other can be used as reference fiber. The temperature ...
متن کاملTemperature- and phase-independent lateral force sensor based on a core-offset multi-mode fiber interferometer.
A novel lateral force sensor based on a core-offset multi-mode fiber (MMF) interferometer is reported. High extinction ratio can be obtained by misaligning a fused cross section between the single-mode fiber (SMF) and MMF. With the variation of the lateral force applied to a short section of the MMF, the extinction ratio changes while the interference phase remains almost constant. The change o...
متن کاملMiniature high-sensitivity high-temperature fiber sensor with a dispersion compensation fiber-based interferometer.
A miniature high-sensitivity, high-temperature fiber sensor with an interferometer based on a bare small-core-diameter dispersion compensation fiber (DCF) is reported. The sensing head is a single-mode-fiber (SMF) DCF configuration formed by a 4 mm long bare DCF with one end connected to the SMF by a fusion splicing technique and the other end cleaved. Due to the large mode index difference and...
