Long-Reach lambda-Tunable WDM/TDM-PON Using Synchronized Gain-Clamping SOA Technology
This paper proposes a 40 Gbit/s class lambda-tunable wavelength division multiplexing and time division multiplexing passive optical network (WDM/TDM-PON) system that uses our newly developed high-output-power lambda-selective burst-mode transmitter (B-Tx) in an ONU and a 4 x 4 cyclic arrayed waveguide grating as a photonic router. Our developed B-Tx utilizes a booster semiconductor optical amplifier that employs a pattern effect suppression technique incorporating synchronized gain-clamping light injection, and it obtains a high output power of over +10 dBm without signal waveform distortion at all wavelength channels. We demonstrate a 40 Gbit/s lambda-tunable WDM/TDM-PON that achieves a 40 km transmission reach and a 40 dB loss budget.
