High output power GaInAsP/InP superluminescent diode at 1.3 μm

Abstract
We have developed a 1.3 μm superluminescent diode using revolutionary structure. A light diffusion surface is placed diagonally on the active layer within the device to suppress the lasing action. Superluminescent diode characteristics were achieved in the range 0–50°C, and the coupled power into a single-mode fibre reached 1 mW.
