Abstract
We prepared numbers of GeAsSe glasses and investigated their thermal stability and optical properties in order to search the best glasses with relatively high glass transition temperature Tg, strong structural stability, low optical loss and high optical nonlinearity. Through our systematical measurements, we concluded that the glasses with a mean coordination number around 2.45-2.5 are the best for the applications in photonics with Tg of 450K, low optical loss of 0.2dB/cm, high optical nonlinearity 7.5×10-14cm2/W and less photosensitivity. © (2015) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
