We propose a novel scheme using a microring resonator (MRR) structure in silicon photonics (SiP) for the elimination of signal-to-signal beat interference (SSBI) in a direct detection, optical orthogonal frequency division multiplexing (DDO-OFDM) system. Unlike other SSBI cancellation techniques, SiP-based MRR shows unique advantages such as compactness and low cost. We examine performance as a function...
We propose a silicon photonics (SiP) enabled interference cancellation scheme for orthogonal frequency division multiplexing (OFDM) using direct detection. System performance is evaluated by sweeping the signal-to-carrier ratio, guard band, and SiP component parameters.
We experimentally demonstrate and evaluate an optimization strategy of a recirculating frequency shifting (RFS) optical comb for terabit flexible optical networks. We achieve an increased optical signal-to-noise ratio (OSNR) with good stability (no system outage) by reducing erbium-doped-fiber amplifier gain in the shifting loop and deploying an in-loop noise suppression filter. We demonstrate that...
We investigate constellation-induced SNR gain in short-reach OFDM with direct detection for various distances and laser linewidths. Performance improvement by using alternate constellations is more significant for lower quality lasers, especially for 8-QAM. As transmission distance increases, higher SNR gain is obtained (1.92dB for 100km).
