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.


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.


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.


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.
