Burst-mode wavelength upconversion using gain-clamped SOA for applying WDM technique to TDM-PON

We propose a WDM/TDM-PON utilizing AOWC. ~23 nm multiple- to single-wavelength upconversion for 1.25 Gbit/s burst-mode signals is realized by GC-SOA. The measured optical equalization is >8 dB and average latency is <;1.2 ms.
