Abstract : The DURIP funds generously provided by the AFOSR were used to set up a state-of- the-art facility for fabricating in-fiber photorefractive and planar waveguide surface etched Bragg gratings. These gratings are being investigated for such defense-relevant projects as high temperature sensors, distributed and multiplexed strain and temperature sensors, bio-agent sensors and wavelength division multiplexed telecommunication systems. In this report, we briefly describe (1) the fundamentals of Bragg gratings in fibers and in planar waveguides (2) the grating fabrication facility made possible by DURIP funding and (3) our progress on the grating fabrication process in the following sections.
