High‐Performance Integrated Optics with Tellurite Glasses: Status and Prospects

Tellurite glasses have long been recognized as interesting materials for fiber 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 realize its promise.
