Abstract
In this communication, we report on the direct inscription of near-surface waveguides in crystals and polymers for the first time. A Ti-Sapphire femtosecond laser was used to form near-surface waveguides based on a depressed cladding architecture in quartz by placing a cover glass temporarily in optical contact with the surface of the sample during the inscription process. Also, a novel technique based on resonant absorption of polymers in the mid-IR is applied to induce the formation of on-surface waveguides in polymers. As a proof of concept, the near-surface waveguides were used as highly sensitive refractometric sensors.
