Abstract

We report integrated coherent optical receivers designed specifically for RF Photonics applications. These receivers may be implemented in either single- or dual-polarization (DP) systems which utilize I/Q (in-phase, quadrature) phase modulation. The integrated receivers incorporate a monolithic 90 degree optical hybrid followed by eight high power-handling InGaAs photodiodes. Linear operation to +27 dBm of total optical input power, 20 mA photocurrent per diode, output third-order intercept (OIP3) > 40 dBm, third-order harmonic distortion < -100 dBc, and RF bandwidths > 4 GHz is presented. Such photoreceiver power-handling and linearity is required to optimize the photonic system spurious free dynamic range (SFDR), noise figure (NF) and link gain.
