Abstract
WE WILL REVIEW RECENT ADVANCES IN THE REALIZATION OF WIDE BANDWIDTH, HIGH PERFORMANCE. FREQUENCY COMB SOURCES BASED ON QUANTUM CASCADE LASERS OPERATING BOTH IN THE THz AND MID-IR REGIONS OF THE E. M. Spectrum. In the Mid-IR, a grating compressor is employed to obtain pulses from a quantum cascade comb operating in CW. IN THE THz, COPPER-BASED DOUBLE METAL WAVE GUIDES ALLOW COMB OPERATION ABOVE LIQUID NITROGEN TEMPERATURE WITH RELATIVE Comb BANDWIDTHS OF 25%. Frequency COMB CONTROL BY MEANS of RF INJECTION AND COUPLED CAVITY SCHEMES WILL BE PRESENTED TOGETHER WITH NEW COMB characterization TECHNIQUES.
