Passive and hybrid mode locking in multi-section terahertz quantum cascade lasers
New Journal of Physics, 2018 It is believed that passive mode locking is virtually impossible in quantum cascade lasers (QCLs) because of too fast carrier relaxation time. Here, we revisit this possibility and theoretically show that stable mode locking and pulse durations in the ...
