Summary form only given. UV-written sampled gratings have recently been demonstrated in optical waveguides. The reflection spectrum of a sampled grating consists of a series of peaks, with a spacing inversely proportional to the sampling period. Within a limited frequency range the dispersion may be ignored and the frequency spacing can therefore be assumed constant. This makes sampled gratings useful for wavelength-division multiplexing (WDM) applications. We demonstrate the application of a sampled grating for a multi wavelength optical add/drop multiplexer, which drops wavelengths spaced by 400 GHz around a center wavelength of 1557 nm.
