Abstract:

In order to reduce the loss of fluorinated polyimide AWG (Arrayed Waveguide Grating) wavelength division multiplexer, guide the AWG experimental preparation, which can meet the demand of low loss communication system, a detailed analysis of influence of structural parameters on fluorinated polyimide AWG multiplexer was done. Array aperture is an important design parameter of the phased array waveguide grating multi/demultiplexer. The transmission characteristics of a fluorizated polyimide AWG multiplexer are analyzed. The diffraction efficiency of the device in the I/O (Input and Output ) slab waveguides is calculated. The effects of some structural parameters including waveguide aperture on the transmission characteristics are investigated and discussed. The AWG structure parameters were optimized and the diffraction efficiency is about 100%.

Key words: array aperture, diffraction loss, diffraction efficiency, parameters optimization
