KAPAH

From medical to telecommunications, terahertz (THz) waves are already making a revolution despite the existence of a tunable, pure, and modular source. KAPAH offers a simple technology that meets all these points and generates THz waves of exceptional quality from 0,1 to 2 THz.

The laser’s spectral refinement by optical feedback is a technology developed at LIPhy for almost 20 years. It allows, by photo-mixing of two low phase noise lasers to generate very pure THz waves.

• Industrial and commercial advantage: largely fiber-based system.
• Business advantage: extremely tunable and spectrally fine instrument.
• Ecological advantage: electricity consumption significantly lower than the competition.

Given that the laboratory system is robust and agile, that its physics is well understood and that the results meet expectations, it is necessary to move to a phase of miniaturization and optimization which will guarantee the rapid diffusion of the technology in different fields.

THz waves can be used in several applications, in particular for:

• Defense for detecting hidden non-metallic objects and for monitoring radar systems
• Telecommunications to achieve the performance levels required for 6G and beyond
• Medical imaging, THz allows medical imaging applications that are as precise and less harmful than X-rays or UV.
