Abstract
A production method of an optical waveguide includes: preparing a laminated body that includes a first clad layer and at least a core layer laminated on the first clad layer; forming a light propagating optical waveguide core by cutting the core layer by use of a dicing saw from a side where the core layer is laminated while intruding an edge of a blade portion of the dicing saw into the first clad layer so as to partially cut the first clad layer; and embedding at least a cut portion of the laminated body with a second clad layer.
Claims8
A production method of an optical waveguide, comprising:
- preparing a laminated body that comprises a first clad layer and at least a core layer laminated on the first clad layer;
- forming a light propagating optical waveguide core by cutting through the core layer by use of a dicing saw from a side where the core layer is laminated while intruding an edge of a blade portion of the dicing saw into the first clad layer so as to partially cut the first clad layer;
- and
- embedding at least a cut portion of the laminated body with a material of a second clad layer.
A production method of an optical waveguide, comprising:
- preparing a laminated body that comprises a first clad layer and, on the first clad layer, at least a core layer and a third clad layer laminated in this order;
- forming a light propagating optical waveguide core by cutting through the core layer and the third clad layer by use of a dicing saw from a side where the core layer and the third clad layer are laminated while intruding an edge of a blade portion of the dicing saw into the first clad layer so as to partially cut the first clad layer;
- and
- embedding at least a cut portion of the laminated body with a material of a second clad layer.
