摘要：

A guided-wave Mach-Zehnder interferometer structure, based on the use of a four-port hybrid optical coupler consisting of symmetric and nonsymmetric y junctions, is proposed for wavelength-division multiplexing application. This structure provides less sensitivity to fabrication parameters and optical polarization, and can also be applied to a wide-wave-length spacing operation. Interferometers for wavelength splitting in the 1.3 and 1.55-mu-m windows were designed and fabricated into a glass substrate with a dry silver ion exchange process. The measured crosstalk was -30 dB with nonpolarized light.
