摘要:

A wavelength filter consisting of two dissimilar rib waveguides is analysed with respect to the waveguide response and tuning. An optimised structure with a 0.41 nm bandwidth and a 9 mm coupling length is designed. Two techniques are developed to model tapered filters, where the guide separation is varied to improve the wave-length response. A good agreement is found between both methods.
