Abstract
A coherent receiver module is presented, comprising
two optical 90$^{\circ}$ 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.
