RF Photonic systems handle photonic and electromagnetic waves, being the only technology today enabling continuous generation of Terahertz signals where vast amounts of bandwidth are available. However, as frequencies increase, also increases the complexity of the characterization and packaging of these systems. Current efforts are towards the development of standardized packaging solutions within Packaging Pilot Lines, providing fiber array access ports and multiple DC electrical connections. However, RF applications are still lagging behind, considering that Beyond 5G aiming to move at frequencies above 100 GHz. This is a major problem since there are few RF connector solutions at higher frequencies, with coaxial standards reaching up to 110 GHz (1-mm connector) and rectangular waveguides segmenting the spectrum into bands defined by flange size. In this workshop we will discuss state-of-the-art for characterization and packaging of photonic Terahertz systems.

This workshop is organized around the TERAmeasure Pathfinder Open EU project (www.uc3m.es/research/terameasure), developing photonic-driven technologies for Terahertz instrumentation. The goal is to develop a photonic-based Vector Network Analyzer operating beyond 1 THz. The workshop provides an overview of why we need these systems, and the current challenges that are faced when developing devices and systems operating above 100 GHz, with key speakers addressing the different components (high-speed photodiodes, detectors), the integration of antennas and the assembly challenges.
