• Subjects: DEVICES OR ARRANGEMENTS, THE OPTICAL OPERATION OF WHICH ISMODIFIED BY CHANGING THE OPTICAL PROPERTIES OF THE MEDIUM OF THEDEVICES OR ARRANGEMENTS FOR THE CONTROL OF THE INTENSITY,COLOUR, PHASE, POLARISATION OR DIRECTION OF LIGHT, e.g.SWITCHING, GATING, MODULATING OR DEMODULATING; FREQUENCY-CHANGING; NON-LINEAR OPTICS; OPTICAL ANALOGUE/DIGITAL CONVERTERS; OPTICAL ELEMENTS, SYSTEMS, OR APPARATUS; OPTICAL LOGIC ELEMENTS; OPTICS; PHYSICS; TECHNIQUES OR PROCEDURES FOR THE OPERATION THEREOF

PROBLEM TO BE SOLVED: To prevent a sagging or a crack of an incidence plane of a laser beam of a ridge optical waveguide wavelength conversion element. SOLUTION: The method for manufacturing an optical waveguide wavelength conversion element includes at least: a step of forming grooves which intersect perpendicularly with a periodic polarization inversion stripe to form a ridge; a step of cutting a substrate into blocks each including a plurality of optical waveguide wavelength conversion element chips; a step of supplying hot melt wax to the ridge face of the block; a step of loading a dummy substrate to the ridge face of the block; a step of melting the hot melt wax, while pressing the block and the dummy substrate; a step of cooling, while pressing the block and the dummy substrate; a step of grinding a ridge end face; a step of polishing the ridge end face; a step of detaching the dummy substrate; and a step of dividing the block into single optical waveguide wavelength conversion element chips.
