Coherent Receiver

Integrated Coherent Receiver combines polarization beam splitting optics for the 

signal and local oscillator inputs, two matched optical 90° hybrids with monolithically 

integrated balanced photodetectors, and four linear trans-impedance amplifiers (TIAs) 

with differential outputs in a compact surface-mount package. The receiver is available 

in both C- and L-band versions.

The device separates the incoming signal in X and Y polarization channels. Optical 90° hybrids

 subsequently demodulate the incident signal for each polarization into its in-phase (I) and 

quadrature (Q) phase channels, relative to an external local oscillator laser source. The phase 

channels are converted to electrical signals by pairs of balanced photodetectors that are 

monolithically integrated with the optical 90° hybrids, and subsequently amplified by linear 

trans-impedance amplifiers (TIAs). The TIAs feature integrated peak detectors and support 

both manual and automatic gain control.
