A coherent receiver module is presented, comprising two optical 90° hybrids monolithically integrated with eight waveguide p-i-n photodiodes in balanced configuration and two dual-channel linear transimpedance amplifiers. Its performance is demonstrated by transmitting up to 160 Gb/s dual-polarization quadrature phase-shift keying signals over 610 km standard single-mode fiber.
