The authors demonstrate a widely tunable grating-assisted codirectional coupler (GACC) based receiver in the InP/InGaAsP materials system. With current injection of only 20 mA into each filter section, the integrated receiver can be continuously tuned over a 30 nm wavelength range. To the best of the authors knowledge, this is the highest tuning range reported so far for an InP/InGaAsP GACC tunable receiver.
