Title
A novel cost-effective combline generation and cross-talk mitigation in optical OFDM signal using optical iFFT circuits
Abstract
This paper is focused on the proposed novel techniques for cost-effective and high performance optical OFDM systems. We propose a novel cost-effective optical comb-line generation source to produce 8-sub-carriers with spectral flatness of <;1dB with drive amplitudes of 1Vpi employing single dual-drive Mach-Zehnder-Modulator and show a comparison with other efficient comb-generator methods. We also propose a novel optical iFFT-based implementation for 87.5 Gbit/s optical NRZ-OFDM generations. It is shown that the cross-talk introduced by imperfect WDM demultiplexer to separate sub-carriers for modulation can be significantly reduced.
