Rate equation model of the negative characteristic temperature of InAs∕GaAs quantum dot lasers

The negative characteristic temperature of InAs∕GaAs quantum dot lasers is studied using a rate equation model. It is found that the decrease in the total contribution to lasing following a decrease in temperature is the reason for the occurrence of negative characteristic temperature in these laser...
