Bragg grating transmission filters were fabricated on ZnMgSSe-ZnSSe-ZnMgSSe planar optical waveguide structures using a high resolution electron-beam lithographic process. Varying the grating geometry, the filter characteristics like resonance wavelength, modulation contrast, and stopband width can be adjusted. For example, for a L=600-/spl mu/m-long grating with a period of /spl Lambda/=120 nm, we achieve 16% residual transmission and a spectral width of 4 /spl Aring/ for the designed resonance wavelength of 603 mm. The experimental data can be explained quantitatively with a transfer matrix calculation assuming a coupling coefficient of 40 cm/sup -1/.
