Paper Abstract

The nonlinear contribution into the diode resistance in addition to the nonlinearity of injecting p-n junction is considered associated with a carrier injection into some nominally passive regions adjacent to the active region of the device (effect of the injection-induced conductivity, IIC). A condition the IIC to give a substantial contribution is availability of resistive passive layer or depleted layer in the diode chip that can be undergone to a conductivity modification by carrier injection and leakeage. There are some consequences that look like unusual features: (i) anomaously large the non-ideality factor of I-V curve; (ii) anomalous electrical response on the variation of the optical feedback in the laser diode device; (iii) anomalous sign of the threshold-related kink of the differential resistance of laser diode.
