Recent progresses on hybrid InP/Si integration are presented for achieving high-performance tunable transmitters for cost-sensitive wavelength division multiplexing access networks. We demonstrate the generation of on-off keying non return to zero modulation format using several types of integrated directly modulated and tunable lasers. The use of the high output power hybrid silicon transmitter enables up to 28.5 dB optical budget at BER = 3.8 x 10(-3) (in-band FEC assumed) under 10 Gb/s direct modulation over 25 and 50 km. Long-reach transmission over 100 km single-mode fiber is also demonstrated. Based on an enhanced modulation bandwidth hybrid laser, we successfully achieve 21.4 Gb/s direct modulation including FEC overhead on 12 wavelengths over a short-reach access link (10 km).
