3D interferometric integrated structure for all-optical wavelet transform

Resumo

In this paper, we present the design of a 3Dinterferometric structure based on a planar waveguides network, able to optically perform the wavelet decomposition of two dimensional input data, such as image pixels. The possibility to implement a system that could offer potential in terms of integrability and robustness is explored. This idea is supported by the existence of methods and optical architectures, based on interferometric structures, for the implementation of the optical wavelet transform. They enable parallel processing on one dimension of the input data and they can be enhanced with the development of structures able to parallelize the processing on two dimensional data.
