摘要：

Asymmetric Mach-Zehnder channel waveguide interferometers possessing a 1.1 ns delay in one of the arms were fabricated using dame hydrolysis deposit;ion of silica glass on silicon. Two modules were combined to form a single time-division interferometer for optical pulses. The composite interferometer exhibited a high fringe contrast ratio of 1:200 making ii eminently suitable for use in compact, low error-rate quantum cryptography systems.
