Design and Operation of Optical Fiber for Mass Measuring Instrument with Bending Power Loss Principle

Abstract

Utilization fiber optics macro-bending will be useful for non-destructive applications, such as a mass measurement device. This research, therefore, analyzes the fiber optic power loss due to macro bending by mass loading and explores its possible application as an instrument of mass scale. A single-mode fiber (SMF) with a core diameter of 8.2μm and laser with a wavelength of 1310 nm and 1550 nm are used in this work. Moreover, an optical power meter with a sensitivity of 0.01dBm is applied as the detector while power loss is determined using nine bending cylinders that can produce eighteen bends with a roundtrip system. It is obtained a correlation coefficient R 2 of 0.9910 and 0.9959 corresponding to a sigmoid of 4 parameters for two-wavelength sources of 1310nm and 1550nm, respectively. The results showed mass suppression can produce a power loss with a relatively small error of 19.60%,

Design of a Flexible Weight Sensor Using Optical Fibre Macrobending

“…In [ 20 ] a mass measurement scale was built by laying single mode fibre in between a fixed lower set of 8 mm radius cylinders, and a further set of cylinders suspended from a weighing platform mounted on springs. By adding weights to the upper platform, the fibre was bent in between the two rows of cylinders, and the macrobending loss could be read.…”

Multiple inputs all-optical logic gates based on nanoring insulator-metal-insulator plasmonic waveguides

“…Despite the widespread use of plasmonic in all-optical processing, several disadvantages remain, such as substantial metal resistive losses; as a result, plasmonic systems are known as lossy systems when it comes to surface plasmon polaritons (SPPs), losses limit their wave propagation length to a few nanometers or micrometers at the most [3]. Interference between waves in input and control waveguides at cavity resonance wavelengths serves as the basis for operation [4]. The phase of the incident light wave at inputs and control ports will be tuned, and the total propagation losses in each state of activation will be modified correspondingly, to realize the behavior of all-optical logic gates according to their truth tables.…”
