The 100 GHz narrow band pass filter (NBP filter), the total number of the layers being 187, is deposited by electron gun with ion-assisted deposition (IAD). When we grind, polish and cut the filter to 1.4 mm/spl times/1.4 mm/spl times/1 mm chips, the stress release curves the chip surface, and shifts the central wavelength of the NBP filter spectrum about-0.9 nm. The spectral shift can also be simulated by optical thin film program.
