El-Darawy M, Pfau T, Wördehoff C, Hoffmann S, Noe R. Realtime QPSK transmission with an integrated coherent optical receiver frontend. In: IEEE Photonics Society, ed. Photonics Society Summer Topical Meeting Series, 2011 IEEE. Piscataway, NJ: IEEE; 2011: 115-116.An integrated coherent receiver frontend is compared to a fiber-pigtailed 90° hybrid in a realtime QPSK transmission experiment. Additionally the impact of carrier recovery filter width and phase deviations in the 90° hybrid is analyzed
