The Research activities developed in the LAHC laboratory are in the fields of Science and Technologies of Communication and Information and Applied Physics.

In this domain,  techniques, as well as software and hardware technologies, change in a very fast way. The improvement of hardware performances is related to the development of new technologies and to the rise in frequency and bandwidth of associated devices and systems.

The drastic evolution of speed and dimensions of electronic circuits, as well as the explosion of the needs of communication tools in the radio frequency range, require to bring breakthrough solutions to issues connected to high-speed and high-frequency signal processing and propagation.

Since its creation 15 years ago,the laboratory is focused on the resolution of these issues; it is located at the crossing between microwave, optoelectronics and nanoelectronics worlds.

LAHC is a laboratory focused on applications: we model, simulate, generate  and characterize fast or ultra-fast signals. Depending on the applications, the spectrum covered by these signals ranges from Megahertz (MHz) to several Terahertz (THz) frequencies. The associated techniques deal with ultra-high-frequency electronics and optics, often used jointly.

Our basic skills rest on electronics, ultra high frequencies (microwave techniques), optics and optoelectronics, superconductive electronics, electromagnetism and applied Physics.
