| Abstract: | A statistical optimization method for the design of a fluorinated polyimide wavelength division element for optical communications is proposed. The optimized device is an interleaver element suitable for dividing over 40 wavelengths in the 1550 nm band. Optimization considers the inherent polarization dependence of fluorinated polyimide based on measurements of the dispersion characteristics and birefringence of fluorinated polyimide film. A 40 wavelength device is designed using the proposed technique, for a working wavelength of 1550 nm and a wavelength interval of 0.8 nm. The device exhibited 1 dB passband of 0.5 nm and 3 dB passband of 0.8 nm, and output wavelength fluctuation due to polarization effects of less than 0.08 nm. |
