Accurate Measurement of Forward Electrical Characteristics in Laser Diodes

Abstract
The dependence of series resistance,ideality factor,junction voltage,and capacitance on the applied voltage or current of laser diodes (LDs) is determined by examining forward AC behavior together with I-V characteristics.The experimental results,for the first time, demonstrate that the junction voltage saturation occurs after the junction voltage, series resistance, ideality factor,and junction capacitance simultaneously show step offsets near the threshold.A negative capacitance effect in LDs is also observed under larger voltages or lower frequencies. -
