Title:
WAVELENGTH CONVERSION LIGHT SOURCE DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/058599
Kind Code:
A1
Abstract:
A device is provided with a semiconductor gain medium (1) having an inclined or curved stripe structure, a Volume Bragg Grating element (3) constituting a resonator with the semiconductor gain medium (1), and a wavelength conversion element (5) which outputs a harmonic wave (H) of a fundamental wave (A) from the resonator. Preferably, the semiconductor gain medium (1) is a frequency incoherent and wideband semiconductor gain medium, the wavelength conversion element (5) is a cyclic polarization type nonlinear wavelength conversion element, and the Volume Bragg Grating element (3) and the cyclic polarization type nonlinear wavelength conversion element (5) have a grating cycle having a chirped structure.
