Paper Abstract

This analytical modeling-and-simulation paper presents a compact passive photonic filter using Mach-Zehnder Interferometer (MZI) on silicon-on-insulator (SOI) platform. MZI based wavelength filters have been demonstrated for broadband wavelength-division-multiplexing (WDM). The imbalance in MZI provides means to control the free spectral range (FSR) hence enabling designing of a photonic filter that can pass the required band and block the rest of the signal. Low loss Y-splitter/combiner are used with very small footprint to make compact size MZI. A 3D Finite-Difference Time-Domain (FDTD) simulation is performed on our design. FSR value of 50 nm was observed in the span of 100 nm wavelength range centered on 1.55 μm. The footprint of the designed filter is 15 μm x 20 μm.
