Effect of glow discharge plasma on step index polymer optical fiber parameters

Double Langmuir probe measurement of plasma parameters in a dc glow discharge

In this paper, plasma main characteristics such as electron mean temperature, electron number density, and oscillation frequency have been measured experimentally using the double Langmuir probe diagnostic system. In our experiment, the plasma was generated by applying the low pressure dc glow discharge in several common gases. The experimental results indicated the highest plasma density and o...

Graded-Index Polymer Optical Fiber (GI-POF)

Plastic Optical Fiber Perfluorinated graded-index polymer optical fibers (GI-POFs) combine high data transmission rates and low attenuation in the commercially desirable 850–1300nm range. GI-POFs offer a direct replacement and a low cost alternative to traditional glass. With ease of use and affordability, GI-POFs make an excellent choice for the installation of high performance fiber networks....

One step multifunctional micropatterning of surfaces using asymmetric glow discharge plasma polymerization.

Micropatterning of surfaces with varying chemical, physical and topographical properties usually requires a number of fabrication steps. Herein, we describe a micropatterning technique based on plasma enhanced chemical vapour deposition (PECVD) that deposits both protein resistant and protein repellent surface chemistries in a single step. The resulting multifunctional, selective surface chemis...

Surface Modification of Ag Nano Composites Polymer Membranes by Glow Discharge Plasma

Graded-index polymer optical fiber for high-speed data communication.

We successfully obtained a high-bandwidth (1 GHz km) and low-loss (90 dB/km at 0.572 µm of wavelength) graded-index polymer optical fiber by using the interfacial-gel polymerization technique, in which we used an unreactive component to obtain the quadratic refractive-index distribution. This high-bandwidth graded-index polymer optical fiber makes it possible to transmit a high-speed optical si...
