We have demonstrated a photonic integrated circuit with an InGaAs/InGaAsP multiple quantum well (MQW) traveling-wave optical amplifier and a grating-assisted vertical-coupler filter as a noise filter. A fiber-to-amplifier/filter gain of ∼ 0.5 dB and a 3 dB filter bandwidth (FWHM) of ∼ 70 Å at 1.56 μm filter center wavelength have been achieved. This photonic circuit is potentially suitable as a building-block for preamplifier lightwave receivers or high-gain, high-power optical amplifiers which are essential for optical communication systems and lightwave networks.
