- Abstract
- Active and passive optical waveguides are fundamental elements in modern telecommunications systems.
A great number of optical crystals and glasses were identified and are used as good optoelectronic
materials. However, fabrication of waveguides in some of those materials remains still a challenging task
due to their susceptibility to mechanical or chemical damages during processing. Researches were initiated
on ion beam fabrication of optical waveguides in tellurite glasses. Channel waveguides were written
in Er:TeO2-WO3 glass through a special silicon mask using 1.5 MeV N+ irradiation. This method was
improved by increasing N+ energy to 3.5 MeV to achieve confinement at the 1550 nm wavelength, too.
An alternative method, direct writing of the channel waveguides in the tellurite glass using focussed
beams of 6-11 MeV C3+ and C5+ and 5 MeV N3+, has also been developed. Channel waveguides were fabricated in undoped eulytine-(Bi4Ge3O12) and sillenite type (Bi12GeO20) bismuth germanate crystals using
both a special silicon mask and a thick SU8 photoresist mask and 3.5 MeV N+ irradiation. The waveguides
were studied by phase contrast and interference microscopy and micro Raman spectroscopy. Guiding
properties were checked by the end fire method. (literal)
