Integrated photonic devices based on metallic nanoparticles in dielectric crystalss

As the basic components of integrated photonic devices, optical waveguides on dielectric crystals have attracted considerable interests among researchers in the last few decades. Compared with the bulk material, optical waveguide shows prior optical properties owing to its high optical intensity in a small volume, which leads to the lower lasing thresholds and higher slope efficiencies in the application of laser generation. As the important part of the pulsed laser system, metallic nanoparticles can be served as saturable absorber due to the excellent SPR absorption. It is deserved to expect the combination of optical waveguide and metallic nanoparticles for the pulsed laser generation.
