Impact of “Ghost” Mode Interaction in Terahertz Quantum Cascade Lasers

Mode degeneration caused by the interaction between guided lasing modes and parasitic “ghost” modes in a terahertz (THz) quantum cascade laser (QCL) waveguide has been investigated and is reported here. It is shown that such interactions can degrade the performance of a QCL by...
