Abstract :
We report on all-fiber tunable terahertz (THz) signal generation based on a tunable Micro Electro-Mechanical System Vertical-Cavity Surface-Emitting Laser (MEMS-VCSEL) and a fixed wavelength VCSEL. The VCSELs pump a n-i-pn-i-p supperlattice broadband photomixer. Signals between 33 GHz and 690 GHz were successfully generated, with no fundamental limit towards larger tuning ranges.
