We demonstrate a tunable wavelength optical waveguide filter with a Bragg grating on a low-loss polymer waveguide. To control the peak wavelength of the Bragg reflector, an electrical power is applied to the device electrode so that the effective index of the polymer waveguide is change by the joule heating
