Light Communication with ultra-high-speed organic optoelectronic devices and transparent antennas

The project aims to explore and build resilient tomorrow’s free-space light communication systems based on disruptive organic optoelectronic components. High-speed Organic optoelectronic devices are available across the entire visible spectrum, and compared to inorganic III-V counterparts, they offer lower manufacturing costs, shorter time to market and a lower carbon footprint, and exhibit at least similar or better performance in terms of transmission data rates. Another advantages is the very easy and low-cost heterogeneous integration of OLED on silicon (or on any other substrate). In contrast, inorganic (III-V) components, can only be integrated with compatible substrates due to the well-known lattice mismatch problem. This enables the integration of organic optoelectronic components on CMOS ASICs unleashing a new range of functionality.
A scientific and technological revolution is at hand with the emergence of ultra-fast organic optoelectronics and photonics on glass and on integrated circuits. High-speed micro-organic light emitting diodes (HS-µ-OLED) exhibit modulation bandwidths as high as 500MHz, enabling to transmit data above 4Gbit/s. Additionally, these new components are capable of handling short optical pulses of 400ps. These promising results suggest that bandwidths up to and above 1 GHz can be achieved.
The current project aims to design, fabricate and integrate into light communication systems, matrices of high-speed µOLEDs along with organic photodetectors (OPD) and transparent antennas on the same substrate for example on a glass windows. Advanced modulation waveforms with non-linearity management compatible with the new IEEE 801.11bb LiFi standard will be implemented to reach transmission rates greater than 10Gbit/s per channel.
The expected multiple-input-multiple-output (MIMO) light communication system will include an optically transparent RF receiver front-end for the realization of the RF to free-space Optics continuum.
