Monolithically integrated distributed feed back laser diode for e.g. optical transmitting module, has rear facet with inclination angle, where laser and monitor diodes are switched in conducting and blocking directions, respectively

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.
