On the nonlinear theory of coherent generation in resonant tunneling diodes

The nonlinear theory of generation in a resonant tunneling diode is develop ed for a frequency range of omega < Gamma, where Gamma is the width of the resonant level. This frequency interval is usually implemented in experimen ts. The generation power of a resonant tunneling diode is calculated analyt ically as a function of the pumping current and the diode parameters. It is demonstrated that there exists no limitation on the generation power. The soft and hard generation regimes as well as hysteresis phenomena are predic ted.
