Demonstration of an 8×25-Gb/s optical time-division multiplexing system

An 8×25-Gb/s optical time-division multiplexing (OTDM) system is demonstrated experimentally. The optical pulse source is based on optical frequency comb (OFC) generation and pulse shaping, which can generate nearly chirp-free 25-GHz 1.6-ps optical Gaussian pulse. The eightfold optical time-division...

Description
Summary:An 8×25-Gb/s optical time-division multiplexing (OTDM) system is demonstrated experimentally. The optical pulse source is based on optical frequency comb (OFC) generation and pulse shaping, which can generate nearly chirp-free 25-GHz 1.6-ps optical Gaussian pulse. The eightfold optical time-division demultiplexer consists of a single-driven dual-parallel Mach–Zehnder modulator (DPMZM) and a Mamyshev reshaper. Error-free demultiplexing of 8×25-Gb/s back-to-back (B2B) signal with a power penalty of 4.1 dB to 4.4 dB at a bit error rate (BER) of 10−9 is achieved to confirm the performance of the proposed system. •25-GHz 1.6-ps optical Gaussian pulse without nonlinear compression is achieved.•Error-free eightfold time-division demultiplexing is experimentally performed.•Requirement of switching window is significantly reduced with Mamyshev reshaper.•The ultra-short clock signal is not required for demultiplexing.
