3D Nanodruck
Nature Photonics: In situ 3D nanoprinting of free-form coupling elements for hybrid photonic integration

March 2018: Scientists of IPQ and IMT have demonstrated microscopic beam-shaping elements that can be directly printed to the facets of optical chips or fibers by means of multi-photon lithography. The beam shaping elements comprise free-form lenses and mirrors as well as more complex multi-lens systems such as beam expanders. Facet-attached optical elements can dramatically relax alignment tolerances of optical coupling interfaces, thus paving the way to automated assembly of photonic multi-chip systems with unprecedented performance and versatility.

Corning Outstanding Student Paper Competition: Grand Prize goes to Christoph Füllner

March, 2018: The OSA Foundation and Corning Inc. announced the winners of the annual Corning Outstanding Student Paper Competition at this year's Optical Fiber Communications Conference (OFC 2018), the largest conference and exhibit for optical communications and networking, with more than 15,500 attendees, 700 exhibitors from 65 countries, and over 850 peer reviewed technical presentations.

Christoph Füllner, PhD candidate at the IPQ, won the Grand Prize for his paper "Transmission of 80-GBd 16-QAM over 300 km and Kramers-Kronig Reception Using a Low-Complexity FIR Hilbert Filter Approximation" in a fierce competition among around 220 PhD submissions and five finalists.

The Corning Outstanding Student Paper Competition has been established in 2007. With three Grand Prize winners (2010, 2013, and 2018) and two honorable mentions (2012, 2016), the IPQ is demonstrating global leadership in the field.

Post-Deadline Paper with IPQ Contributions Accepted at OFC 2018

March 15, 2018: A collaboration of researchers from the University of Paderborn, the Heinz Nixdorf Institut in  Paderborn and KIT-Institute of Photonics and Quantum Electronics presented their postdeadline paper "64 GBd Monolithically Integrated Coherent QPSK Single Polarization Receiver in 0.25µm SiGe-Photonic Technology" the most recent results on a monolithically integrated coherent receiver at this year’s Optical Fiber Communications Conference (OFC) in San Diego, California, USA. 

OFC Post-Deadline papers represent the latest groundbreaking technical achievements in the field, and only a few are selected by a panel of experts in a highly competitive process. OFC is indisputably the world's leading global conference and exposition for optical communications and networking professionals

Optical Distance Measurement
Science: Ultrafast optical ranging using microresonator soliton frequency combs

February 2018: Scientists of IPQ and École polytechnique fédérale de Lausanne (EPFL) have demonstrated the fastest distance measurement so far. The researchers demonstrated on-the-fly sampling of a gun bullet profile with micrometer accuracy. The experiment relied on a soliton frequency comb generated in a chip-based optical microresonator made from silicon nitride. Potential applications comprise real-time 3D cameras based on highly precise and compact LIDAR systems. The publication appeared in Science Vol. 359, Issue 6378 today on 23 February 2018.

Prof. Dr. Christian Koos
ERC Consolidator Grant for Prof. Dr. Christian Koos

November 2017: Prof. Dr. Christian Koos received the ERC Consolidator Grant for his project TeraSHAPE (Terahertz Waveform Synthesis and Analysis Using Hybrid Photonic-Electronic Circuits). TeraSHAPE aims at establishing the foundations of novel signal processing concepts at T-wave frequencies between 100 GHz and 1 THz and at combining massively parallel processing in digital electronic circuits with synthesis and analysis of broadband waveforms in the optical domain.

The ERC awards funding to excellent investigators looking to set up or consolidate their own independent research team or programme to pursue ground-breaking, high-gain/high-risk research. The project of Prof. Dr. Christian Koos was selected among 2 538 submissions.

Preisträger 2017
Gips Schüle Research Award 2017 goes to Sascha Mühlbrandt, Christian Koos and Manfred Kohl

November 2017: The IPQ/IMT team received the Gips Schüle Research Award (50.000 €) for their work on plasmonic internal photoemission detectors (PIPED). These devices combine ultra-compact footprint with electro-optical bandwidths of hundreds of GHz and have the potential to act as ultra-fast interfaces between optical and wireless communication networks. The Gips Schüle Research Award honors and supports outstanding performance in applied research in the area of “People and Technology” and is awarded biannually by the Gips Schüle Foundation.
