Investigation of bending and temperature effects in optical fibers

Abstract

Fiber bending and temperature loss mechanisms in plastic optical fibers are reported.A simple arrangement is used to monitor the fiber bending and temperature by output power variation. Powers in the fibers in bend‐free situation at room temperature and under rolling deforming force at different water bath temperatures (20–60°C) are measured and compared. Reported arrangements can be used as a temperature sensor. © 2012 Wiley Periodicals, Inc. Microwave Opt Technol Lett 55:82–86, 2013; View this article online at wileyonlinelibrary.com.

Beam shape and intensity profile of a fiber-bundle prism-coupled waveguide

“…Thermal consideration on the design and operation of lens ducts has been reported [18]. In the following study [19] investigation of surface radius variation in design of a lens duct delivery system reported recently. More details in this respect can be found in other reports by author and others.…”

Comparison of two triple‐fiber sensor designs for small distance measurements

“…Fiber optical sensor has been reported in literature for different applications . Numbers of optical designs are reported by author, which are based on the intensity modulation method using fibers as a waveguide . Advantages of the plastic optical fibers (POFs) such as the ease of operation, cost factor, and precise performance requirements have led to the application of all plastic double‐fiber design .…”

“…It was found that transmission loss for the coated single mode fibre increased steeply at low temperatures (Katsuyama et al, 1980). Golnabi and Sharifian (2013) reported that the optical loss is affected by the fibre dimension, materials, the radius of the bent fibre and the wavelength of the light. The experimental setup is shown in Figure 2.7, where the light source used in the experiment was a white LED, and laser diode and the temperature was in a range from 20°C to 60°C (Golnabi and Sharifian, 2013).…”

“….7. Setup of the experiment carried out byGolnabi and Sharifian (2013).The result inFigure 2.8 shows that the transmitted power of a rolled fibre is lower than that of an unrolled fibre, indicating that the bent fibre can result in fibre transmission loss. The other outcome of the experiment demonstrated that the transmitted power for a bent fibre varied with the temperature of the fibre(Golnabi and Sharifian, 2013).…”
