Microstrip-antenna-coupled distributed feedback terahertz quantum-cascade lasers
By introducing coupled microstrip antennas on THz Distributed Feedback (DFB) Quantum Cascade Lasers (QCLs), the radiation efficiency of each feedback aperture is greatly enhanced. Single mode emission ∼3 THz from a 31-period antenna-coupled third-order DFB laser yields ∼4 times improvement in output...
