SUPERLUMINESCENT DIODE, OPTICAL INTERFERENCE TOMOGRAPHIC IMAGING DEVICE COMPRISING THE SAME, AND METHOD OF CONTROLLING SUPERLUMINESCENT DIODE

摘要

PROBLEM TO BE SOLVED: To provide an SLD (superluminescent diode) capable of controlling an optical output and a spectral shape of SLD light in a short time with ease and with accuracy when an upper electrode or a lower electrode is configured by a plurality of electrodes.;SOLUTION: A superluminescent diode comprises: an optical waveguide layer having a lower clad layer, an active layer, and an upper clad layer on a substrate; and an upper electrode and a lower electrode for making the active layer emit light. The superluminescent diode has such a configuration that the upper electrode or the lower electrode has a plurality of electrodes, and partial light in a plurality of light-emitting regions formed so as to correspond to the plurality of electrodes enters into the active layer of the other light-emitting region. A light receiving part for detecting a quantity of spontaneous emission light from at least one light-emitting region is arranged adjacently to the light-emitting region.;COPYRIGHT: (C)2014,JPO&INPIT
