SUPER-LUMINESCENT DIODE, MANUFACTURING METHOD FOR THE SAME AND OCT DEVICE USING THE SUPER-LUMINESCENT DIODE AS LIGHT SOURCE

摘要

PROBLEM TO BE SOLVED: To provide a super-luminescent diode having high breakdown resistance that can control the shape of a wavelength spectrum and achieve high output.;SOLUTION: A super-luminescent diode has an active layer constituting an optical waveguide and outputs from the emission side of the optical waveguide spontaneous emission light which is amplified while propagating through the optical waveguide. The super-luminescent diode has laser beam irradiating means for irradiating the optical waveguide with a laser beam from the outside of the optical waveguide to set the active layer to an excitation state, plural LEDs which are configured to change the shape of spontaneous emission light propagating through the optical waveguide and emit light having different wavelengths respectively, and an optical absorption region that is formed in an area at an end portion side of the optical waveguide opposite to the emission end face of the optical waveguide and attenuates return light.;COPYRIGHT: (C)2012,JPO&INPIT
