SMART-electron

ULTRAFAST ALL-OPTICAL SPATIO-TEMPORAL ELECTRON MODULATORS: OPENING NEW FRONTIERS IN ELECTRON MICROSCOPY (SMART-electron):
Addressing the grand-challenges that the world is facing nowadays in connection with ‘energy’, ‘information’ and ‘health’ requires the development of unconventional methods for unprecedented visualization of matter. SMARTelectron aims at developing an innovative technological platform for designing, realizing and operating all-optical rapidly-programmable phase masks for electrons. By introducing a new paradigm where properly synthesized ultrafast electromagnetic fields will be used for engineering the phase space of a free-electron wave function, we will be able to achieve unprecedented space/time/energy/momentum shaping of electron matter waves, surpassing conventional passive monolithic schemes and revolutionizing the way materials are investigated in electron microscopy.

SAMOA-NET

SpAtial Multiplexing in Optical Access NETworks (SAMOA-NET):
Within the scope of the BMBF programm „Forschung Agil – Raummultiplexing in faseroptischen Netzen“, the SAMOA-NET consortium (HOLOEYE Photonics AG, Heinrich-Herz Institut, Heraeus Quarzglas, VI Systems, VPIphotonics and Nokia Solutions and Networks) aims at comprehensively investigating transmission using spatial multiplexing over multicore optical fibers in the optical access network and show how bottlenecks can be overcome in the future. Based on a jointly developed system concept, the partners will develop the components essential for data transmission. These include long-wavelength VCSEL and photodetector arrays, the multicore fiber, flexible coupling into and out of the multicore fiber using spatial light modulators, and MIMO signal processing.

WESORAM

WEllenlängenselektive Schalter für Optisches RAumMultiplex (WESORAM):
Within the scope of the BMBF programm „Forschung Agil – Raummultiplexing in faseroptischen Netzen“, the WESORAM consortium (HOLOEYE Photonics AG, ADVA Optical Networking and Fraunhofer IOF) proposes an economically viable solution to the steadily increase in need of data rates in optical network. The approach chosen consists in using spatial division multiplexing (SDM) while avoiding increasing the number of optical subsystems. For this, we are developing a new compact 8×16 Wavelength Selective Switch (WSS) for the C-Band able to perform switching of any of the inputs to any of the outputs with a granularity of 12.5GHz.

SLM4OAM

Räumlicher Lichtmodulator bei 2,1µm Wellenlänge für die Freistrahlkommunikation mittels Kodierung über den Bahndrehimpuls (SLM4OAM):
Free-space data transmission using laser radiation can be used wherever a broadband, interference- and tap-proof alternative to radio transmission is required and at the same time the use of optical fibers is ruled out, e.g. due to a lack of infrastructure or in the case of relative movement between transmitter and receiver (e.g. satellite communication). Within the scope of the project SLM4OAM, HOLOEYE and ifnano e.V. Göttingen are demonstrating a new free-space, eye-safe, robust communication line. The methods is based on the use of vortex beams. The information is coded using the orbital angular momentum of the photons. The light is modulated using a LCOS-Type SLM especially developed for the 2100nm wavelength range.

MB-HAR-B

Mechanical micro-drilling tools currently can be used to drill holes up to a diameter of around 10 μm at a drilling depth of approximately 100 μm. The main issue with mechanical drills is the long processing time required per hole, the short service life of the drilling tool caused by wear and the aspect ratio.

In order to create small boreholes with a high aspect ratio, it is possible to use Bessel beams, which have the property of being almost diffraction-free over a relatively long beam propagation length. The central maximum of the Bessel beam is also narrowly limited, which enables small diameter drilling holes.

MaMeK

The aim of the MaMeK (Projektionssysteme für die Maschine-Mensch-Kommunikation / Projection systems for machine-human communication) joint project is to research and develop two technological approaches for displays, as well as their analysis and evaluation for integration into a Car2Human communication concept. The aim is to develop holographic direct view displays and highly efficient ground projection systems which enable a dynamic display of information.
