英文摘要 | ABSTRACT The invention concerns AlGalnP/GalnP visible laser diodes and LEDs withimproved maximum output power. This is achieved by embedding the activeregion of the diode (30), e.g. a GalnP active layer (35), between very thin p- andn-doped AlGalnP barrier layers (34.1, 34.2) and thick p- and n-doped AlGaAscladding layers (33, 36). The inventive barrier layers (34.1, 34.2) are employedto avoid tunneling and spill over of carriers from the active region (35) into thecladding (33, 36). These barrier layers (34.1, 34.2) can be very thin thus allowingbandgap engineering and providing for barriers with low defect density. Inaddition the low resistance of the AlGaAs cladding reduces the thermal andelectrical resistances of the device. |
