FemtoLab is an ultrafast high speed laser spectroscopy and communication laboratory in the physics department at Stevens Institute of Technology, Hoboken, NJ. The lab director is Rainer Martini.

Main focus of the research in this laboratory is development of new devices and application in the infrared region of the spectrum. A specific focus is thereby on security as well as communication application.

[edit] Mid-Infrared Free-Space Optical Communication

In a long term study the laboratory compares since 2001 the atmospheric propagation at different wavelengths in indoor and outdoor studies to find the optimal wavelength for free-space optical communication. It specifically uses Quantum cascade laser to transmit data using the mid-infrared part of the spectrum, which propagates much more favorably under bad weather conditions like fog.

[edit] Optical controlled devices for the Terahertz system

A secondary focus of research is based on the component development for the far-infrared spectral region, the so called terahertz spectrum. This components are including modulators and lenses and are based on optical excitation and allow therefore for an active control.
