Abstract

Two difterent concepts for 1.30- and 1 .55-μm dual-wavelength demultiplexers/multiplexers, based on glass waveguides, the symmetric directional coupler, and the asymmetric Mach-Zehnder interlerometer, are analyzed and compared. Attention is given mainly to the sensitivity to fabrication parameter changes. The rather strict fabrication conditions needed to obtain satisfactory performance from directional couplers are examined. With Mach-Zehnder interferometers, the sensitivity is considerably lower, which indicates that the fabrication of these devices is uncomplicated.
