Superluminescent diodes

Four superluminescent diodes serve as light sources for fiber-optic gyroscopes, optical current transformers, otdrs, and other optical measuring instruments. All have output characteristics that are designed between those of laser diodes and LEDs. They have a wider, smoother spectral emission than LDs and launch a higher intensity into an optical fiber than do LEDs. All feature high optical output with low operating current and wide spectral half-widths with low coherence length. They are available at wavelengths of 780 and 840 nm. Wavelengths of 1300 and 1550 nm will be available this spring. Models SD1S552P, SD1S101C, SD1S306P, and SD1S501P come in a variety of packages, including can, cylindrical, and butterfly.
