A long-period waveguide grating based on a low-loss negative tone epoxy Novolak resin (ENR) polymer has been fabricated on SiO/sub 2//Si substrate. A transmission peak of -13 dB at /spl sim/1.5 /spl mu/m wavelength was observed for a grating length of 1.7 cm. Thus, LPWG exhibits a relatively small size and similar performance to the long-period fibre grating (LPFG), and provides integration with various optical components and functional devices on the same SiO/sub 2//Si substrate.
