Abstract
The invention relates to an all-optical demultiplexer for an optical orthogonal frequency division multiplexing (OFDM) signal having a centre wavelength. The OFDM signal comprises a plurality of subcarriers, each subcarrier having a symbol rate. The demultiplexer is adapted for spectrally magnifying the OFDM signal and comprises a first time lens, a second time lens, and a dispersive element. The dispersive element is arranged in a signal path between the first time lens and the second time lens to form a time lens telescope. The invention further relates to a method of demultiplexing OFDM signals.
