“…The 3-dB modulation bandwidth of the EAM is beyond 100 GHz, and the modulation linearity supporting multilevel modulation formats was verified [10,11]. Besides the DFB-TWEAM, other broadband components of 3-dB bandwidth over 100 GHz are also prototyped during the HECTO project, including limiting driver amplifiers, 2:1 multiplexers and photodetectors [12]. Together with the DFB-TWEAM, these broadband components can relax the channel bandwidth limitations to a great extent, which potentially release the DSP complexity by offering better signal quality.…”

“…The tranmission line design of the electrode does not only increase the overall device size when compared to a lumped driven modulator, but also necessitates a power consuming 50Ω termination. The same transmitter as in [9] was used to for a real-time 100 Gb/s NRZ link in [11]. Unfortunately, the transceiver modules were developed for metro networks, leading to unrealistic formfactors and power consumptions for use in shortreach optical interconnects.…”

Transceivers based on electro-absorption modulators are considered as a promising candidate for the next generation 400 GbE short-reach optical networks. They are capable of combining high bandwidth and low-power operation with a very compact layout, removing the need for traveling wave electrodes and dedicated 50 Ω termination. In this paper we demonstrate the first silicon-based EAM, in combination with an in-house developed SiGe BiCMOS transceiver chipset, capable of transmitting single-lane 100 Gb/s non-return-to-zero in realtime. Transmission up to 500 m of standard single mode fiber and 2 km of non-zero dispersion shifted fiber is demonstrated, assuming a forward-error coding scheme with a bit-error rate limit of 3.8×10 −3 is used. Due to the high line rate, transmission over longer fiber spans was limited by the chromatic distortion in the fiber. As a possible solution, electrical duobinary modulation is proposed as it is more resilient to this type of fiber distortion by reducing the required optical bandwidth. We show improved performance for longer fiber spans with a 100 Gb/s electrical duobinary link, resulting in real-time sub-FEC operation over more than 2 km of standard single-mode fiber without any digital signal processing. Finally, the possibility of a 100 Gb/s EAM-to-EAM link is investigated.

“…Most of the components such as TIA, drivers and photodiodes are now able to provide a bandwidth suitable for 100-GBd single wavelength applications [1]. Nevertheless, modulators suffer from strong frequency-dependent loss and their 3-dB bandwidth hardly reaches 60 GHz for the best of them [2], [3].…”

We report a continuous-time analog equalizer based on a differential cascode amplifier cell. Realized with indium phosphide double heterojunction bipolar transistors reaching a fT/fmax couple of 370/340 GHz, this circuit exhibits a maximal peaking of 10.5 dB at 85 GHz. The tunability is made thanks to a varactor, which can tune the peaking frequency from 30 to 85 GHz. This analog equalizer also provide a bandwidth of more than 110 GHz whatever the varactor settings, which makes it suitable for very high speed applications.
