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 λ_1,MOD to λ_N,MOD. Each waveguide comprises at least two optical resonators configured such to realize a wavelet filterbank so that the modulated optical signals λ_1,MOD to λ_n,MOD undergo WT/IWT in a manner such to obtain optical wavelet transformed signals that can be orthogonally frequency division multiplexed or demultiplexed.
