Tunable line-narrowed lasers employing Y-junction waveguide resonators

Abstract

Rare-earth-doped planar waveguide lasers have been realised in many host materials, using a range of waveguide fabrication techniques. Recent advances in this technology exploit the advantages that planar devices have over fibre devices. In particular, electro-optic or thermo-optic modulators may readily be monolithically integrated, complex devices may be defined photolithographically, there is access to the modal fields for surface interactions, and waveguide geometries may be varied along the device for efficient interfacing to external components and for optimisation of individual components on an optical "chip".
