Paper Abstract

Incorporation of active materials, such as Neodymium (Nd3+) and Erbium (Er3+) in suitable host media has potential applications in lasers and amplifiers. We have fabricated composite planar waveguides on glass substrates doped with Nd3+ and Er3+ ions using the sol-gel process. The composite sol-gel was prepared using polyvinylpyrrolidone as the organic part, while Tetraethyl orthosilicate and Titanium isopropoxide formed the inorganic part. The samples were prism coupled and it was found that they supported single mode at (lambda) equals 633 nm. Gain measurement of the Nd3+ samples have also been carried out.
