Abstract	:	Narrow bandfdters are important elements of integrated optical circuit. Resonantcavities imbedded between two identical parallel waveguides result in compact narrowband Add/Dropfilter. In this thesis work, such add/dropfilters are analyzed using theMethod of Lines (MOL).Add/drop filter with square, circular and elliptical cavities areinvestigated. The spectral response of the four port filter and the power loss spectrum areobtained. The MOL using the Layer by Layer Algorithm is applied to model the add/dropfilters. In addition, the MOL with improved features is presented in this work. Thisincluded improved implementation of the transverse second derivative operator and theincorporation of a Perfectly Matched layer (PML).Calculated results show that the Add/dropJilter with an embedded circular cavity givemuch better spectral response when compared to the square and elliptical cavities.Almost complete optical power drop from the bus to one of the receiver ports can beachieved in the circular cavity case.Keywords: Method ofLines (MOL), Perfectly Matched Layer (PML), Narrow BandFilter, AddDrop Filter, Directional Coupler.Master of Science DegreeKing Fahd University of Petroleum and Minerals, Dhahran.April 2005,.............-....,....-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
