FULL-OPTICAL MULTIWAVELET ORTHOGONAL FREQUENCY DIVISIONAL MULTIPLEXING (OFDM) AND DEMULTIPLEXING

摘要

Aspects of embodiments relate to an optical wavelet transform (WT) or inverse wavelet transform (IWT) medium for implementing optical multiwavelet orthogonal Frequency Division Multiplexing (OFDM) or optical demultiplexing. In embodiments, the optical WT/IWT medium comprises a plurality of N waveguides for receiving in parallel a corresponding number of N modulated optical input signals λ1,MOD to λN,MOD. Each waveguide comprises at least two optical resonators configured such to realize a wavelet filterbank so that the modulated optical signals λ1,MOD to λN,MOD undergo WT/IWT in a manner such to obtain optical wavelet transformed signals that can be orthogonally frequency division multiplexed or demultiplexed.
