Abstract
Waveguides written in active glasses and that incorporate Bragg gratings form the basis of a stable, monolithic waveguide laser platform fabricated at Macquarie University. Previously we have demonstrated single wavelength structures based on ytterbium doped phosphate glasses; these allow laser operation near 1030 nm and with output powers of several hundred milliwatts [1]. The distributed-feedback laser devices can be unidirectionally or double-end pumped and the balance of laser power emitted from the facets is controlled by the position of a phase shift in the grating structure.
