A cost-efficient hybrid-integrated receiver is demonstrated. The optical signal routing as well as the optical mixing of the signal input and the local oscillator employing multimode interference couplers (MMI) is realized in a polymerbased photonic lightwave component (PLC). The results of chip-level measurements exhibited photodiode responsivities of approximately 0.06 A/W and a polarization extinction ratios (PER) of greater than 20 dB.
