Laser Diode Characteristic Curve

Home / Laser Diode Characteristic Curve

One of the most commonly used and important laser diode specifications or characteristics is its L/I curve. This plots the drive current supplied on the horizontal axis against the light output on the vertical axis. The light-current-voltage (L-I-V) sweep test is a fundamental measurement that determines the operating characteristics of a laser diode (LD). Laser diodes (LD) are semiconductor devices that convert electrical energy into high-power optical energy. We look at I-V characteristic curves for 3 different diodes in butterfly package using the Koheron CTL200 digital laser controller (type 1, 600 mA laser current). The point is exactly the plural form "Rate Equations", because a unique form does not exist. Gain, optical power, threshold, efficiency, and in general all quantities that are relevant for characterizing and monitoring such devices are referred to different representations of injection: separation.
