In this study, a GaN-based light-emitting diode (LED) with a distributed Bragg reflector (DBR) current blocking layer (CBL) beneath the p-pad electrode is demonstrated. A high reflectivity DBR structure is composed of five periods SiO and TiO layers. At a driving current of 20 mA, the light output power of the LEDs with DBR CBL was 16.8% and 11.3% higher than the LEDs without and with SiO...
