Laserdiode with integrated monitordiode

摘要

The diode (LD) has an integrated n-p- or p-n- monitor diode with a laminar active monitor diode layer (MDS). A rear facet (RF) regenerating light has an inclination angle that is larger than 0 degree and smaller than 90 degrees based on an active laser layer (LS) at an angle that is equal to 0 degree. The active monitor diode layer is arranged in an area of the rear facet below the active laser layer between two n-p- or p-n-semiconductor layers, where the laser diode is switched in a conducting direction and a monitor diode (MD) is switched in a blocking direction for the current.
