摘要: Chromatic dispersion characteristics over multiple channels in holographic grating (HG) demultiplexers are modeled and analyzed, theoretically experimentally. The arises from a combination of out-coupling lens aberration the HG phase structure. A theoretical model channel spectrum demultiplexer was assembled, based on first-order Born approximation volume diffraction verified by experimental numerical data. These results show that structure becomes an effective design parameter could be used to control high-performance multiple-channel dense wavelength-division-multiplexing demultiplexer.
