Microsensing of plutonium with a glass optofluidic device

Two-stage method of hollow channels formation inside glass by direct laser writing and selective etching is perspective way for microfluidics devices manufacturing. In this work the influence of the etching solution concentration and laser writing conditions (the laser beam scanning speed, pulse energy) on the etching rate, selectivity and roughness of hollow channels in quartz glass is studied. The use of 1M NaOH makes it possible to increase the etching rate of hollow channels up to 300 µm/h while maintaining high selectivity up to 680.

Ion-exchange on glass is one of the major technological platforms that are available to manufacture low-cost, high performance Planar Lightwave Circuits (PLC). In this paper, the principle of ion-exchanged waveguide realization is presented. Then a review of the main achievements observed over the last 30 years will be given. The focus is first made on devices for telecommunications (passive and active ones) before the application of ion-exchanged waveguides to sensors is addressed.
