| 简介 |
The purpose of the invention is heavy metal oxide thin films and their applications. These thin films will serve to produce doped and undoped planar wave-guides and planar lightwave circuit (PLC) for passive and active optical devices (amplifier, laser, filter, multiplexer, attenuators and….). These thin films present low loss, good chemical and thermal stability and wide optical transmission window, high solubility of all rare earth ions and transition metals ions…. They can be deposited on different substrates. |
