Abstract
The dielectric crystals are important media for diverse optical applications due to their astonishing properties. Miniature photonic devices based on waveguiding structures have been incorporated in broad range of photonic devices that benefit from the excellent properties of crystals. We summarize our recent progress of research on the design and implementation of three-dimensional (3D) waveguiding structures in dielectric crystals by femtosecond laser inscription. With the engineering of the localized material modifications induced by femtosecond laser pulses, structures with on-demand geometries could be manufactured in dielectric crystals. The 3D photonic devices are designed and produced and the functions based on these 3D devices for beam splitting and waveguiding lasing are realized.
