Abstract

The optical gain in a Nichia® group-III nitride based blue laser diode has been measured at room temperature using the variable stripe length method and nanosecond excitation. Except for stripe lengths less than 50 μm the device shows considerable deviation from the expected exponential intensity behavior. However, for short stripe lengths large gain values of up to 650 cm-1 are observed when exciting with 20 MW cm-2. Plasma recombination from a quantum confined level is suggested as the gain mechanism.
