Abstract

An InGaAsP superluminescent diode operating at 1.5 μm wavelength is successfully developed using a buried bent absorbing waveguide structure and antireflection coating to suppress lasing mode. Optical characteristics such as high output power (5 mW at 200 mA), broad-band spectral width (60-70 nm), short coherence length (about 30 μm), and low spectral modulation depth (less than 10%) are achieved. Injection current dependence of emitting wavelength and spectral width are also investigated.
