Polyethylene glycol (PEG) used in the preparation of (Er3 /Yb3 ):LiNbO3 waveguides

Popis výsledku v původním jazyce

LiNbO3 co-doped with Er3+ and Yb3+ belongs among the most promising materials in photonics. In the form of thin films on a suitable substrate, it can be used as an active waveguide. Only few articles have been published concerning the deposition of such thin layers using a sol-gel method. Our aim was to test polyethylene glycol (PEG) as a watersoluble polymer in solutions to be deposited by spin-coating on sapphire substrates. Two heat treatment regimes were tested after single layers were deposited. Photoluminescence in a range of 1450-1650 nm was measured and the final films exhibited emission spectra with 6 local maxima. The deposited (Er3+/Yb3+):LiNbO3 films were also characterized by m-line spectroscopy. In the NIR range, the films behaved as one-mode waveguides. This nonhydrolytic sol-gel method based on PEG thus represents one of few methods applicable in LiNbO3 waveguiding films preparation.
