Optical properties of polymers wikipedia
WebIn optical communications optical fibers allow for transmission distances of more than 100 km without amplification depending on the bit rate and modulation format used for transmission. A very advanced research topic within photonics is the investigation and fabrication of special structures and "materials" with engineered optical properties. Webpolymers that possess unique optical properties to encourage many research groups to take into consideration these polymers to be utilized in optical devices, sensors and LEDs as well. To change the optical properties of certain polymers, it is viable to tune these properties using dopant materials.
