Paper Abstract

One of the current research trends in silicon photonics is to integrate many kinds of optical functionalities on a single chip. In this paper, based on Silicon-on-Insulator (SOI) we design a tunable filtering waveguide consisted of a Fabry-Pérot cavity and a straight waveguide. The Fabry-Pérot cavity is used for wavelength selectivity and the waveguide is used for light guide. The transmission characteristic of the device has been numerically simulated. The result shows that the Full-Width Half-Maximum (FWHM) is inversely proportional to pairs of the DBR. The tunable filtering waveguide can be integrated with waveguide photodetector, and hopefully to be used in WDM system.
