Fiber waveguides, fabrication

An important theme of this volume is the interrelationships among materials chemistry, photonic and optoelectronic properties, and device performance. The design and synthesis of novel polymer compositions and architectures aimed at enhanced properties are emphasized in some chapters. Other contributions feature the development of novel approaches to processing and fabrication of photonic and optoelectronic polymers into thin films, multilayers, fibers, waveguides, gratings, and device structures. These approaches, which emphasize polymer synthesis, processing, and device fabrication, are complementary and synergistic. 

We discuss concepts for a class of switching devices,intended to be easy to fabricate and test, based on combining nonlinear organic solutions with glass fiber waveguides. 

Transparent materials nanocomposites with high refractive index (w 1.65-1.79) and high transparence in visible light region, with transmittance higher than 90%, are potential materials for fabrication of optical fibers, waveguides, lenses, and LED packages [7]. 

The experiment was carried out by a continuously working Nd YAG-laser fabricated by NEC. The laser has a maximum output of 1200 W and is controlled by handling facility with a linear axle. A stage index fiber optical waveguide with a diameter of d=1000 pm was used for the control of the beam. The focusing optics consist of a focusing lens (f=l 16 mm) and a collimation lens (f=70 mm).
