摘要

In this paper, we show a kind of wavelength selective elements for optical communications using linearly chirped moire fiber gratings. According to the coupled-mode theory, the spectral characteristics of linearly chirped moire fiber gratings are studied. By choosing the grating length, the induced refractive index change, and the linear chirp coefficient, various optical transmission filters based on linearly chirped moire fiber gratings can be achieved. These filters are very useful for add/drop operations in wavelength-division-multiplexed (WDM) systems. A novel scheme of optical add-drop multiplexer (OADM) configuration based on linearly chirped moire fiber grating filter is proposed for flexible multiple wavelengths add-drop in WDM systems.
