Characterization of an InP-based electrical 1:2 demultiplexer in a 107 Gb/s OOK system (2009)

Schubert, C., Makon, R.E., Steffan, A.G., Driad, R., Ludwig, R., Schmidt-Langhorst, C.

The system performance of an InP-based electrical demultiplexer within an optically pre-amplified 107 Gb/s OOK receiver is investigated. Error-free performance was achieved in back-to-back...

Hybrid flip-chip integration of a 40 Gb/s DPSK receiver comprising a balanced photodetector on a DLI-SOI board (2008)

Unterborsch, G., Kroh, M., Honecker, J., Steffan, A.G., Tsianos, G., ...

A DPSK receiver concept using flipchip hybrid integration of InP photodetectors on SOI boards with optical decoder is presented. Horizontal waveguiding enables low-cost production for high data rates.

Linewidth investigation of monolithically integrated 40 GHz mode-locked laser diodes for high-speed RZ-DQPSK transmission (2008)

Hüttl, B., Hu, H., Ludwig, R., Kaiser, R., Schmidt-Langhorst, C., Steffan, A.G., ...

The linewidth of an improved 40 GHz modelocked laser diode is investigated. The influence of its operation parameters on linewidth and the resulting performance in a 40Gband-DQPSK system is evaluated.

1.55 mu m Mach-Zehnder modulators on InP for optical 40/80 Gbit/s transmission networks (2006)

Klein, H.N., Chen, H., Hoffmann, D., Staroske, S., Steffan, A.G., Velthaus, K.O.

We demonstrate excellent 40 Gbit/s operation of a packaged InP Mach- Zehnder-modulator with a low rms jitter of 730 fs. A modulator with 63 GHz on-chip bandwidth is shown as a step towards 80 Gbit/s...
