Abstract :
The Letter demonstrates a 1.55 mu m multiquantum well amplifier on an extended InGaAsP passive waveguide with only +or-0.14 dB gain. Reflectivity <8*10-5 from active-to-passive transitions and 41% coupling efficiency from a single-mode fibre are obtained. These amplifiers are suitable for integration with other optical devices in photonic integrated circuits.
