High-Performance Integrated Optics With Tellurite Glasses: Status And Prospects

Tellurite glasses have long been recognised as interesting materials for fibre and integrated optics, but it is only recently that the first steps toward high-performance planar devices have been taken. This study reviews the opportunities for planar tellurite devices, the current state-of-the-art of planar waveguide devices, and considers the areas of research required to move the materials platform to the level of maturity needed to realise its promise.
