Seminar Details


Demonstration of a Cost Efficient Externally Modulated Laser for High Speed Optical Interconnects
Presented by RISE Acreo
We will demonstrate 4PAM high speed transmission with an integrated externally modulated laser (EML) with large bandwidth, paving the way for cost-effective interconnects using high speed multilevel modulation formats.

400G is a Disruptive Technology – and the Time is NOW
Presented by Keysight Technologies
Today’s generation expect to be instantly connected everywhere and at all times – this means the amount of data traffic and speed of delivery has grown exponentially. Traditional copper links and fiber are at their capacity limit. Transition to high amounts of data in the channel mean moves to new transmission techniques like 400G, the next generation communication links used in networks and data centers and applies to both optical and electrical links. Prior speed class jumps (2.5G > 10G > 40G > 100G) were evolutionary increments, but the move to 400G includes a switch to PAM-4 (4 level) signaling which is susceptible to impairments, which means more complex measurements need to be made.
Validation engineers have been asked to shorten design cycles and increase throughput while dealing with limited resources and new technology challenges. Keysight can help make the transition to 400G measurements including Optical Stressed Eye Test, Receiver Test and Transmitter Test. This seminar will review various 400G challenges as well as case studies where these challenges have successfully been addressed.

400GE Adoption: Insights to New Standards and Emerging Form Factors
Presented by Ixia
The IEEE is targeting to release the 400GE specifications this year. Many new concepts [not previously adopted / implemented] have been adopted by the IEEE standards to realize this new Higher Speed Ethernet.
Additionally, there are emerging form factors competing for the hyper scale data center business. The seminar will include insights from IEEE802.3bs standards & 400GE industry adoption by Ixia (now part of Keysight Technologies), the first and only company to successfully implement PAM4 based 400GE line rate traffic.

Polarization Resolved Spectral Measurements for Wafers, Bars and Chips
Presented by Keysight Technologies
With the widespread move to wafer-scale production with integrated photonics technology, the throughput for testing needs to be optimized. A significant part of the time for optical testing on wafers and chips is often used for optimizing the probe coupling. An extra aspect of this for optical coupling involves testing with the intended polarization alignment of the light. Planar devices often have differing optical properties for light polarized parallel (TE) or perpendicular (TM) to the device plane. The difference may be intended for the device functionality or just unavoidable. The coupling from the probe often also has strong polarization dependence, especially with surface grating couplers. Often during initial research and development, this is dealt with by manually aligning the polarization as part of the probe adjustment process. But that quickly becomes a bottleneck for getting fast automated and reproducible results. Especially for spectral measurements of wavelength dependence, the attempt to hold this polarization alignment while the wavelength is scanned is a real challenge for both speed and reproducibility. A powerful way to address this challenge is with fast automated measurements of the complete polarization dependence, from which the results for aligned polarization can be extracted. Development and results on this using Keysight’s tunable laser-based Photonic Applications Suite, which has grown together with the fiberoptic component industry, will be presented.

The Kramers – Kronig Receiver
Presented by University of L'Aquila and Consorzio Nazionale Interuniversitario per le Telecomunicazioni (CNIT)
The Kramers – Kronig receiver has been recently shown to offer unprecedented opportunities in the design of optical transceivers where the demand for high performance is accompanied by the requirement for reduced complexity and cost. We review the operation principles and the various implementations of the KK receiver. These include a direct detection implementation in which the necessary continuous-wave field is transmitted along with the information-carrying signal, and one in which it is added at the receiver and plays the role of the local oscillator of today’s coherent receivers. Schemes for polarization multiplexing with the KK transceiver will also be presented.

10.3 bits/s/Hz Spectral Efficiency 54x24GBaud PM-128QAM Comb-Based Superchannel Transmission Using Single Pilot
Presented by Chalmers University of Technology
We demonstrate transmission of a 14.2Tbit/s comb-based superchannel using a single shared optical
pilot tone. The pilot tone allows for locking the central line between the transmitter and receiver combs,
enabling blind carrier recovery and a spectral efficiency of 10.3bits/s/Hz.

Application of Machine Learning for Test & Measurement Equipment
Presented by Technical University of Denmark
In broad terms, the concept of Artificial Intelligence (AI) applies to machines that are able to perform tasks at human or smarter-than-human level. The AI technology aims to automatize time-consuming routine labor and also, in the long run, tasks that very complex such as finding: correlations and discovering patterns in massive data sets, optimizing large communication networks, calibration of equipment with a large degree of parameters and diagnostics of large-scale systems. Machine learning is a part of AI technologies where data is provided to the machine and the machine is able to learn from the data. In this talk, we will have a look how the latest advances in machine learning can be applied to the field of test & measurement equipment and which new business opportunities could arise. It will be discussed how neural networks can be applied for automatic stress-test signal generation and automatization of the stress-test measurements.

Optical Frequency Noise Measurement for Coherent Applications
Presented by SYCATUS Corporation
The optical frequency noise measurement is essential for the evaluation of the spectral purity of lasers for applications of digital coherent communications and coherent sensing systems. In this session, we present the cutting-edge technologies of the optical frequency noise measurement as well as the comparison with conventional linewidth measurement.

High-Speed Electro-Optical Modulation Using Silicon-Organic Hybrid Technology and Low-Power Digital Signal Processing
Presented by Karlsruhe Institute of Technology
In order to satisfy growing bandwidth demands, high-speed and low-power transceivers suitable for small form-factors are required. At KIT, we recently demonstrated Silicon-Organic Hybrid (SOH) modulators offering record high modulation efficiencies. In a Mach-Zehnder modulator structure, we achieve pi-voltage-length products of 1 Vmm and below. This opens the possibility to drive the modulators directly from CMOS alleviating the need for dedicated driver amplifiers. At the same time, SOH modulators offer a large modulation bandwidth: by combining SOH modulators with digital signal processing we have demonstrated electro-optical modulation at symbol-rates of up to 100 Gbaud. In this presentation, we will review latest progress in SOH modulator technology and discuss how this technology can be utilized in order to build arrays of modulators which offer the path to low-power and scalable Terabit/s-transceivers.
