Now Available. CS-LDTC07: Room Temperature Terahertz Frequency Comb Using QCLs
Researchers at Northwestern University, Illinois have designed a terahertz (THz) frequency comb using a Quantum Cascade Laser (QCL) with a Distributed Feedback (DFB) grating inside the cavity. The DFB grating addition allows for dual wavelength emission from the QCL. A single-mode state and a harmonic comb state combine inside the cavity for a THz frequency comb. Two uses of QCL frequency combs demonstrated by researchers at Harvard University are also discussed.
The complete case study is available as CS-LDTC07.
