Abstract :
Thermal characteristics of InGaN-based blue laser diodes (LDs) emitting around 450 nm are investigated with varying cavity length of the LDs. Characteristic temperature, junction temperature, and thermal resistance are measured for the cavity length from 650 to 1450 m. It is found that the characteristic temperature increases slowly with cavity length, and the thermal resistance is significantly improved from 30 W to 17 K/W as the cavity length increases length from 650 to 1450 m.
