Abstract

We discuss the design of Mach-Zehnder waveguide duplexers for 1300 and 1530nm band-centres using InGaAsP/InP strip-loaded waveguides. We show that this device has a high inherent tolerance to fabrication and waveguide parameter variation. Using a novel configuration of concentrically curved waveguides, better than -11.5dB crosstalk has been achieved in both channels. The performance of the constituent waveguide bends and directional couplers will also be discussed.
