Applications of Acrylate-based Polymer and Silicone Resin on LPFG-based Devices

摘要

Both acrylate-based polymer and silicone resin are proposed as recoating materials surrounding LPFGs for purposes of different applications. For the LPFG recoated with a thin layer of acrylate-based polymer, the range of wavelength shift as much as 60nm is expected when temperature changes from 0～100℃. As for that with surrounding material of silicone resin, the temperature stability is greatly improved depicted as the maximum wavelength shift of about 0.6nm with the same temperature variation. The former is potentially a broadband tunable band rejection filter or temperature sensor with enhanced sensitivity. And the latter could be applied as temperature insensitive filter, demultiplexer or strain sensor.
