Christensen, Douglas A. | Laser diode coherence length variation with drive current: a tool for dispersion measurements | A visible light (670nm) laser diode was used as a variable coherence length source to measure dispersion characteristics in single-mode fibers. The diode's spectral width, measured against increasing drive current, was found to change from about 16 nanometers to less than 0.2 nanometer. The corresp... | Laser diode; Fiber interferometry | 1992 |
