Title:
SPOT SIZE CONVERTER AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/105712
Kind Code:
A1
Abstract:
The present invention provides a spot size converter that couples optical waveguides of different sizes with high efficiency and low loss, and has high axial misalignment resistance and design flexibility. A spot size converter coverts a beam diameter between optical wires of different core sizes, and comprises: a first surface optically connected to a first optical wire of a first size; a second surface optically connected to a second optical wire of a second size larger than the first size; and a tapered polymer waveguide the diameter of which conically decreases from the first surface toward the second surface.
