Abstract

We numerically demonstrate that the classical thin film computation method (Abeles Computation Method) may be used to obtain reflectance or transmittance of integrated optics filters with a good approximation. Radiative losses are simulated by absorption losses. Results agree well with Film Mode Matching computed optical properties and the computation time can be divided by a factor of 10⁴. Synthesis of integrated Bragg reflectors, narrow band pass filters, high pass filters is presented. Integrated optics filters with non-periodic structures such as gain flattening filters can be easily designed using the Abeles Computation Method. Thus, classical thin film synthesis softwares are useful to design integrated components with arbitrary guided mode spectral reflectance or transmittance. This leads to prospects of new integrated optics functionalities of a great importance such as broadband dispersion compensation for WDM systems or high - order dispersion compensation with non linearly chirped integrated Bragg reflectors.
