The coherent photodetector device consists of an integrated polarization beam splitter and four balanced photodiodes pairs, monolithically integrated with optical 90° hybrids. The photodetector is fully differential, optical front-end suited for up to 64 GBaud polarization diversity x-QAM measurement applications, and features a high common mode rejection ratio. The optical 90° hybrids demodulate the I/Q incident signal for each respective polarization state utilizing external reference oscillator laser sources.

The photoreceiver module FT-RV2022(A) is a single ended front-end with a high gain of typically 500 V/W and a bandwidth of 33 GHz. The photoreceiver module FT-RV2022(A) contains a waveguide-integrated PIN-photodiode (PD) and a transimpedance amplifier (TIA) with limiting output buffer. An integrated feedback loop optimizes the performance in the frequency and/or time domain with respect to different optical input power. Due to the limiting output buffer the output voltage swing is limited to approx. 400 msV. Incorporated blocking capacitors enable AC output coupling.

F-tone Networks’s CPRV2b22A 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. At the signal input there is a monitor photodiode for input signal monitoring, as well as a variable optical attenuator (VOA). 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.
