Abstract
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 low sensitivity to fabrication parameters and optical polarization and can also be applied to wide wavelength spacing operations. Interferometers for wavelength splitting in the 1.3 and 1.55 micrometers 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.
