摘要：

Analysis of effect of temperature on the blue laser diode characteristics at 507 nm emission wavelength has been carried out in the temperature range 273-300 K using indigenously developed computer simulation tools. Dependence of threshold voltage, threshold current and the output power on the temperature has been investigated. It has been resolved from the present analysis that the threshold voltage needed for the lasing in the blue laser diode increases linearly with the corresponding increase in temperature. Temperature dependent current characteristics explicate exponential increase in threshold current with increase in temperature. It reveals that the output power decreases in nonlinear manner with an increase of temperature. Present analysis shows decrease in differential quantum efficiency eta(d) with corresponding increase of temperature for the cavity length of 700 mum. (C) 2003 Published by Elsevier B.V.
