چکیده
It is shown the "single-mode-multimode-single-mode" structure allows carrying out remote temperature measurement with optical time domain reflectometer. A multimode fiber length was 10 mm. We used range from 30 to 70 o C and wavelengths of 1310 1550 nm. The total a single-mode fiber-optic line for reflectometric measurements 20 km. Keywords: optics, optic sensors, reflectometry, interference.

Fiber refractometer based on a fiber Bragg grating and single-mode-multimode-single-mode fiber structure.
A refractive index (RI) sensor based on a novel fiber structure that consists of a single-mode-multimode-single-mode (SMS) fiber structure followed by a fiber Bragg grating was demonstrated. The multimode fiber in the SMS structure excites cladding modes within output single-mode fiber (SMF) and recouple the reflected cladding Bragg wavelength to the input SMF core. By measuring the relative Br...
متن کاملNew Design of Optical Filters Based on Single Mode-Multimode-Single Mode Fiber Structure for Optical Fiber Communication Systems
In this paper, a design of optical filters based on single mode-multimode-single mode fiber structure (SMS) is demonstrated. The multimode interference effect can be utilized to design wavelength-selective devices with high extinction ratio. The proposed optical filters are realized by using standard optical fibers. Two optical filters are designed to operate with wave division multiplexing (WD...
متن کاملSingle-mode operation of a coiled multimode fiber amplifier.
We report a new approach to obtaining single-transverse-mode operation of a multimode fiber amplifier in which the gain fiber is coiled to induce significant bend loss for all but the lowest-order mode. We demonstrated this method by constructing a coiled amplifier using Yb-doped, double-clad fiber with a core diameter of 25 microm and a numerical aperture of ~0.1 (V approximately 7.4) . When t...
متن کاملA single source microwave photonic filter using a novel single-mode fiber to multimode fiber coupling technique.
In this paper we present a fully tunable and reconfigurable single-laser multi-tap microwave photonic FIR filter that utilizes a special SM-to-MM combiner to sum the taps. The filter requires only a single laser source for all the taps and a passive component, a SM-to-MM combiner, for incoherent summing of signal. The SM-to-MM combiner does not produce optical interference during signal merging...
متن کاملIn-Line Fiber Optic Interferometric Sensors in Single-Mode Fibers
In-line fiber optic interferometers have attracted intensive attention for their potential sensing applications in refractive index, temperature, pressure and strain measurement, etc. Typical in-line fiber-optic interferometers are of two types: Fabry-Perot interferometers and core-cladding-mode interferometers. It's known that the in-line fiber optic interferometers based on single-mode fibers...
