Planar Silica-on-Silicon Waveguide Lasers Based in Two Layer Core Devices

摘要

A monolithic neodymium laser operating in a single longitudinal mode, based on a waveguide core split in two layers to achieve a combination of optimized photosensitivity and rare-earth solubility, is demonstrated, with a lasing threshold of 93 mW and an efficiency of 0.6%.
