Paper Abstract

The purpose of this study is to investigate spatial coherence of superluminescent diode (SLD). In order to measure the spatial coherence, we use an interferometer with double slit. The relation between visibility of the fringe and the diffraction length are reported. Furthermore, difference in spatial coherence between SLD and LED is discussed.
