Low-power (1.5 pJ/b) silicon integrated 106 Gb/s PAM-4 optical transmitter Universiteit Gent
As next-generation data center optical interconnects aim for 0.8 Tb/s or 1.6 Tb/s, serial rates up to 106 GBd are expected. However doubling the bandwidth of current 53 GBd 4-level pulse-amplitude modulation (PAM-4) transmitters is very challenging, and perhaps unfeasible with compact, non-travelling wave, lumped modulators or lasers. In our previous work, we presented an integrated 4:1 optical serializer with electro-absorption modulators ...
Optical transmitter based on a 1.3-mu m VCSEL and a SiGe driver circuit for short-reach applications and beyond Universiteit Gent
Integrated optical transmitter with micro-transfer-printed widely tunable III-V-on-Si laser Interuniversitair Micro-Electronica Centrum vzw
We demonstrate a C-band optical transmitter with an integrated widely-tunable III-V-on-silicon laser on the imec iSiPP50G platform using micro-transfer printing. Back-to-back operation at 40 Gbit/s non-return-to-zero On-Off keying over the C-band is presented. (C) 2021 The Author(s)
Realistic opto-mechanical simulation and tolerancing of an automotive optical transmitter coupling system Vrije Universiteit Brussel
The advent of Plastic Optical Fibre (POF) opened perspectives for numerous applications in the field of datacommunications. POF is increasingly popular in the automotive industry as a robust, lightweight, electromagnetic interference free, easy and cheap to install alternative to electrical wiring for high-speed entertainment, navigation and data acquisition systems in cars. The main challenge for the introduction of datacommunication systems ...
Design of high-speed integrated transmitter circuits for optical links Universiteit Gent
Segmented optical transmitter comprising a CMOS driver array and an InP IQ-MZM for advanced modulation formats Universiteit Gent
Recent developments of transmitter and receiver integrated circuits for optical front-ends Universiteit Gent
Design of automotive VCSEL transmitter with on-chip feedforward optical power control Universiteit Gent
Electro-optic co-design for next generation silicon optical transmitters Universiteit Gent
This paper discusses our progress on high-speed optical transmitters for next generation intra-datacenter interconnects. Silicon integrated photonic systems have a key role to play in this evolution by allowing compact, fast, innovative and cost-effective devices to be manufactured in large volumes. Especially silicon Mach-Zehnder modulators are a very attractive candidate: they are easy to manufacture, easy to use and support both intensity as ...
