| titleOfInvention | Ion exchange glass-based surface type sectional type spot size converter |
| abstract | An ion exchange glass-based surface type sectional type spot size converter is formed by sequentially cascading n sections (n is more than or equal to 2) of glass-based tapered waveguide chips; each section of the glass-based tapered waveguide chip is composed of a glass substrate (100) and a surface type tapered ion doped region (102) inside the glass substrate; the cross section size of the thick end of the surface type conical ion doping region (102) in the nth section of glass-based conical waveguide chip is matched with the cross section size of the thin end of the surface type conical ion doping region (102) in the nth-1 section of glass-based conical waveguide chip, and the thin end of the surface type conical ion doping region (102) in the nth section of glass-based conical waveguide chip is used as the output end of the mode spot converter. The utility model discloses can realize the spot size conversion by a larger margin, improve the device performance to further reduce the degree of difficulty of design and preparation. |
