摘要：

We have fabricated optical directional couplers using titanium-diffused waveguides for which the coupling strength is carefully weighted along the device. With a Hamming function weighting, -25-dB transfer response sidelobes have been obtained, a 17-dB reduction over the uniform coupling case. Sidelobe reduction results in a significant increase in the performance of directional coupler filters and switches.
