Optically induced fast wavelength modulation in a quantum cascade laser

Gang Chen, Rainer Martini, Seong-wook Park, Clyde G. Bethea, I.-Chun A. Chen et al.
An optically induced fast wavelength shift is demonstrated in a standard middle infrared (MIR) quantum cascade laser (QCL) by illuminating the front facet with a femtosecond (fs) near infrared (NIR) laser, allowing fast optical frequency modulation (FM) for free space optical communication (FSOC) an ...
