Abstract
Recent progresses on hybrid integration of III-V on silicon widely tunable laser technologies are presented for achieving high-performance colorless optical network unit. We demonstrate a symmetric 60-Gb/s aggregate rate wavelength division multiplexing (WDM) passive optical network. The device is tuned on six wavelengths over the C -band. The use of the high output power hybrid silicon transmitter enables up to 30 dB (27 dB) optical budget at BER = 1.10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-3</sup> (in-band forward error correction assumed) under 2.5 Gb/s (10 Gb/s) direct modulation over 25 and 50 km. Long-reach transmission over 100-km single-mode fiber is also demonstrated. We believe that integrated hybrid III-V/Si devices will have important applications for WDM transmission for both short range and long haul optical transmission.
