摘要：
Wavelength filters are essential components for selecting a certain wavelength channel of a WDM optical communication system. To realize wavelength filters with narrow bandwidth and high reflectivity, an apodized grating structure with length of 15 mm and index modulation of 5x10(-4) was designed. The device exhibited a reflectivity of 95%, 3-dB bandwidth of 0.28 nm, and 20-dB bandwidth of 0.70 nm on an 18 mm grating length.
