The design principle of interference filters with multiple transmittance peaks used for wavelength division multiplexing systems is presented. The method for determining the transmittance peak wavelengths is put forward. The characteristics of multiple-peak filters and factors of influence on half-band width and rejection are discussed. The thickness tolerance analysis shows that the multiple-peak filters with good performance can be prepared if the standard deviation of transmittance monitoring signal is less than 0.5%. Measured result of a filter with three transmittance peaks is given.
