In this paper, we describe high-power (> 50 mW), wideband (> 50 nm) 1.3 pm super luminescent diodes (SLDs). This dispels our preconception that an SLD cannot emit high-power light like an LD. The SLDs have a tilted stripe and both facets have a window structure and antireflection coating. This design reduces the spectrum ripple (< 0.4 dB). An SLD module exhibited a high coupling efficiency of over 70 % and a high power of more than 30 mW in a single-mode fiber. These SLDs are suitable for use in optical coherence tomography (OCT).
