Abstract

This paper presents an overview of the Haar Wavelet Transform applied with a Multimode Interferometer. The Haar Wavelet Transform is one of the most used compressing method due to its fast computation and uncomplicated design. It only requires an averaging and differencing method, making it possible to easily decompose and compress an image. Based on Soldano1 self-imaging numerical approach and Besse design,² an 2 x 2 Multimode Interferometer with modified access waveguides is presented as solution. Using Beam Propagation Method simulations, the solution was tested, analysed and applied on an Haar Network.
