“…This electronic IC consists of a 2 channel TIA array fabricated in a 0.13 µm SiGe BiCMOS technology of which only one channel was used. The TIA was optimized in terms of power consumption and linearity to support multi-level modulation [10], [11]. The amplifier can deliver a 300 mVpp differential swing into a 50Ω load, has a bandwidth of more than 17 GHz and consumes less than 160 mW per TIA-channel.…”

Abstract-Avalanche photodetectors (APDs) integrated in a silicon platform have the potential to significantly improve the link budget of optical links compared to conventional p-i-n photodetectors, while only requiring CMOS-friendly biasing voltages. We demonstrate an optical receiver based on a 1310 nm <5 V Germanium APD and a low-power transimpedance amplifier that offers a 5-to-6 dB sensitivity improvement compared to operation in PIN-mode. Sub-FEC transmission using PAM-4 in an amplifier-less link over more than 42 km at 40 Gb/s and over more than 10 km at 50 Gb/s is shown with a commercial directly modulated laser as transmitter.

“…The receiver electronics has multiple gain and bandwidth settings that can be optimized to the needs of the link [12]. For the 28 Gb/s experiment, a silicon-contacted Ge waveguide p-i-n PD integrated with a fast SiGe BiCMOS TIA was used [11,13]. The integrated receiver modulation bandwidth was 25 GHz (Fig.…”

“…In the second part of the paper, we will show 28 Gb/s NRZ-OOK data transmission using the same laser but biased at a higher current in order to enhance its modulation bandwidth and output power. At the receiver side, we have A. Abbasi, B. Moeneclaey, X. Yin, J. Bauwelinck, G. Roelkens, G. Morthier 10G/28G Chirp Managed 20 km Links based on Silicon Photonics Transceivers P used a silicon-contacted Ge waveguide p-i-n PD with an integrated TIA with a combined 25 GHz modulation bandwidth [11,13]. In both cases, the transmission link distance was 20 km of standard single mode fiber SMF-28, and the link was operated in the C-band.…”

High speed directly modulated single mode lasers are becoming important optical components for short reach communication. In order to cover a transmission distance that is required for PON and inter data-center applications, the chirp managed laser (CML) is an attractive transmitter technology. This technology enables to use a directly modulated laser (DML) for longer reach systems, resulting in a smaller footprint, low fabrication cost and lower power consumption. Error free 10 Gb/s non-return-to-zero-on-off-keying (NRZ-OOK) data transmission over 20 km standard single mode fiber (SMF) is demonstrated using a heterogeneously integrated III-V-on-Si distributed feedback laser in combination with a tunable optical filter as a transmitter and a Ge-on-Si waveguide-coupled Avalanche Photodiode (APD) with an integrated transimpedance amplifier (TIA) as a receiver. For inter-datacenter applications, by increasing the bias current of the laser (improving its modulation bandwidth and output power) and using a faster silicon-contacted germanium waveguide p-in photodetector with an integrated TIA, 28 Gb/s NRZ-OOK data transmission over 20 km standard single mode fiber is demonstrated..
