- Abstract:
- The paper presents analysis of an electronic system of a driver with the feedback optical loop used for stabilization of radiation power of a semiconductor light sources such as CW laser diodes (LDs) or light-emitting diodes (LEDs). The analysis has permitted derivation of the strict form of static equation describing the relation between the optical output power and the electrical driving signal. The considerations are based on general feedback analysis procedures. A detail metrological analysis of the influence of instabilities in the parameters of the driver system on the value of the optical power of light source is presented.
