Temperature effects of Mach-Zehnder interferometer using a liquid crystal-filled fiber.
We demonstrated a simple and cost-effective method to fabricate all fiber Mach-Zehnder interferometer (MZI) based on cascading a short section of liquid crystal (LC)-filled hollow-optic fiber (HOF) between two single mode fibers by using automatically splicing technique. The transmission spectra of the proposed MZI with different LC-infiltrated length were measured and the temperature-induced w...
متن کاملDynamic Strain Measured by Mach-Zehnder Interferometric Optical Fiber Sensors
Optical fibers possess many advantages such as small size, light weight and immunity to electro-magnetic interference that meet the sensing requirements to a large extent. In this investigation, a Mach-Zehnder interferometric optical fiber sensor is used to measure the dynamic strain of a vibrating cantilever beam. A 3 × 3 coupler is employed to demodulate the phase shift of the Mach-Zehnder in...
متن کاملA Spiral-shaped Mach-zehnder Interferometric Sensor for Monitoring Thickness Changes in Bioreceptor Layers
The potential of the classical “straight” integrated optical Mach-Zehnder interferometric (IO-MZI) sensor for monitoring thickness changes in bioreceptor layers is large: the achieved resolution in refractive index changes obtained in the past is as low as δn~10 [1], see Fig. 1. The MZI can be made selective after definition of sensing windows in the top cladding and by adding a target specific...

IOMS Group, MESA+ Research Institute, University of Twente, P.O. Box 217, 7500 AE Enschede, The Netherlands. e-mail: [email protected], [email protected] The design of a spiral-shaped Mach-Zehnder Interferometric sensor (sMZI sensor) for refractive index sensing of watery solutions is presented. The goal of the running project is to realise a multi-sensing array by placing ...
متن کاملLabel-free detection of bovine serum albumin based on an in-fiber Mach-Zehnder interferometric biosensor.
We propose and experimentally verify an innovative label-free optical fiber biosensor based on a Mach-Zehnder interferometer for bovine serum albumin (BSA) concentration detection. The proposed fiber biosensor utilized a micro-cavity within a single-mode fiber to induce Mach-Zehnder interference. A remarkable feature of this biosensor is that external media can directly interact with the fiber ...
