SC446 - Hands-on: Characterization of Coherent Opto-electronic Subsystems

Monday, 12 March
08:30 - 12:30

Short Course Level: Beginner and Advanced Beginner

Instructor: Harald Rohde and Robert Palmer; Elenion, Germany

Short Course Description:

In this course, we will discuss the main characteristics of lasers, IQ – modulators, and coherent receivers and elaborate how to characterize and measure those. Advantages and disadvantages of different measurement techniques will be discussed.

In a hands-on section, the instructors present and explain a setup for laser and ICR characterization. Selected parameters of several lasers and of an ICR will be characterized.  Participants who bring their own laptop can evaluate the data from the measurement setup.

Many key properties can only be extracted from measured data by extensive signal processing. Therefore, measurement methods and accompanying Matlab /Octave or Python scripts will be demonstrated. The respective algorithms and sample code will be provided.

Please note that due to cost and logistical reasons only one measurement setup can be provided. The course concentrates on the physical properties of the components, DSP related topics are not covered.

Specified component parameters are usually the way to ensure the required performance of a subsystem. The interdependence of component parameters and system performance can be evaluated by numerical models. Therefore, we recommend to the interested audience SC 395 as a supplement.

Short Course Benefits:

The course enables the participants to understand the properties of key optical components for coherent communication systems. The participants will be able to measure those properties and to evaluate the results in the right context. They will gain a better understanding of component specifications and can specify components themselves.

Short Course Audience:

This course targets researchers and system designers who want to get a better insight into the depths of component properties and to understand the properties’ interdependencies.

Instructor Biography:

Harald Rohde worked on simulation of photonic transmission systems since he joined Siemens in 2001 after receiving his PhD in physics. He followed the various mergers and company splits through Siemens Networks, Nokia Siemens Networks, Coriant and, since 2016, Elenion Technologies. He was working on coherent access systems and moved from this to coherent long-haul systems. He started to develop and implement his own tools to focus on the special needs of the development of a coherent optical access system.  Now he is working on the design and characterization of components for coherent communication systems. He has more than 70 publications and holds more than 50 patents. He is senior member of IEEE.

Robert Palmer received his Diploma degree in physics from the Karlsruhe Institute of Technology (KIT), Karlsruhe, Germany. From 2010 to June 2014 he was a Research Associate at the Institute of Photonics and Quantum Electronics at the KIT, Karlsruhe, Germany, where he was working towards his Ph.D. degree in electrical engineering. In 2013, he received the Corning Outstanding Student Paper Award (first prize) at the Optical Fiber Communication Conference (OFC’13) and the ADVA Best Student Paper Award (first prize) at the European Conference on Optical Communication (ECOC’13) for his work on hybrid integration of Silicon Photonic integrated circuits with organic electro-optic materials.  In 2014 he joined Coriant R&D GmbH, Munich, being responsible for the design and characterization of components for coherent communication systems. He is now with Elenion Technologies. His research interests include integrated optics and coherent communication systems. He has more than 70 publications in scientific journals and conferences.
