N2 - Long-period waveguide grating (LPWG) was demonstrated in polymeric waveguide fabricated on SiO2-Si substrate using standard cleanroom fabrication processes: ultraviolet photolithography and reactive ion etching processes. Experimental results confirm that the relationship between the transmission peak wavelength and the grating period is linear. The LPWG exhibits a maximum attenuation of -18 dB, a minimum 3-dB bandwidth of 6 nm, and the grating length can be as short as 1 cm. The temperature characteristic dλ/dT of the LPWG was also investigated, and is found to be similar to that of long-period fiber grating.
