Abstract

We experimentally demonstrate a novel unified direct and coherent orthogonal frequency division multiplexing (OFDM) scheme. This self-coherent OFDM scheme simplifies receiver architecture and provides interchangeability between direct and coherent receivers using the same unified transmitter. We have experimentally verified the resilience of this scheme to fiber nonlinearities and achieved receiver sensitivity improvement of up to 1.73 dB as compared to the conventional intensity modulation and direct detection OFDM scheme. We have also verified the effectiveness of a dual-analyzer-based balanced detection scheme.
