英文摘要	This paper reports the fabrication of j-shaped bent-waveguide superluminescent diodes utilizing an inalgaas/algaas quantum dot active region. the emission spectrum of the device is centred at 884 nm with a full width at half maximum of 37 nm and an output power of 18 mw. by incorporating an al composition into the quantum dot active region, short-wavelength superluminescent diode devices can be obtained. an intersection was found for the light power-injection current curves measured from the straight-waveguide facet and the bent-waveguide facet, respectively. the result is attributed to the conjunct effects of the gain and the additional loss of the bent waveguide. a numerical simulation is performed to verify the qualitative explanation. it is shown that bent waveguide loss is an important factor that affects the output power of j-shaped superluminescent diode devices.
