We discuss the results on development of very-high output power, wide and flat spectrum superluminescent diodes (SLD) and singlemode fiber pigtailed modules at different spectral ranges. It is shown that by optimizing of SLD design and using by nearly 100% laser diode-consistent SLD technology and structure, it is possible to obtain from SLDs the same outputs as that of fluorescent fiber-doped sources. Using of common approach to SLD design, singlemode fiber outputs up to 20 - 30 mW are realized at 680 - 980 nm spectral bands, with very flat Gaussian-like spectrum and extremely low residual Fabry-Perot modulation depth. Up to 10 mW power is realized at 1300 nm using the same approach. Further possibilities, like SLD spectrum broadening and others, are also discussed.© (1999) COPYRIGHT SPIE--The International Society for Optical Engineering.
