Abstract
We report a new quantum dot superluminescent diode with a new device structure. In this device, a multi-mode-interferometer configuration and a J-bend structure were monolithically integrated. Owing to the multi-mode-interferometer structure, the superluminescent diode exhibits 60% increase in output power and 43% reduction in the differential resistance compared with the uniform waveguide width superluminescent diode fabricated from the same wafer. Our device produces an emission spectrum as wide as 103.7 nm with an output power of 2.5 mW at 600 mA continue-wave injection current. This broadband emission spectrum makes the axial resolution of the optical coherence tomography system employing the superluminescent diode to 6 μ m in theory, which is high enough for most tissue imaging. -
