Abstract
We report on the fabrication process and the application potential of epoxy-based waveguide Bragg grating sensors on low-modulus polymer substrates for low-cost environmental seismic sensing purposes. EpoCore photoresist channel waveguides are fabricated on a highly flexible TPX polymethylpentene polyolefin substrate by means of standard i-line photolithography. Bragg gratings are permanently inscribed into the strip waveguides by KrF excimer laser irradiation using commercially available phase masks. From these raw sensor chips, a linear accelerometer sensitivity of 107 pm/g in a broadband detection range of at least 0.025 - 15 g could be observed. The enhanced seismic sensing capabilities of the Bragg grating sensor scheme are demonstrated by the use of a simple spring mass system.
