Abstract
A polymer optical waveguide includes: a core; and a cladding enclosing the core and extending along a direction of light propagation, the polymer optical waveguide having a substantially rectangular parallelepiped shape, and the polymer optical waveguide having, at least at a position near one end thereof in a longitudinal direction, a groove that has a surface inclined at an angle of 45° with respect to the light propagation direction which reflects light propagating through the core so as to change the light propagation direction by 90°.
Claims12
A polymer optical waveguide comprising:
- a core;
- and
- a cladding enclosing the core and extending along a direction of light propagation,
- the polymer optical waveguide having a substantially rectangular parallelepiped shape, and
- the polymer optical waveguide having, at least at a position near one end thereof in a longitudinal direction, a groove that has a surface inclined at an angle of 45° with respect to the light propagation direction which reflects light propagating through the core so as to change the light propagation direction by 90°.
A method of producing a polymer optical waveguide, comprising:
- preparing a polymer film having a core and a cladding enclosing the core and extending alone a direction of light propagation;
- and
- cutting the polymer film in a thickness direction thereof using a blade having a surface inclined at an angle of 45° at a blade edge thereof so as to form a groove having a surface inclined at an angle of 45° with respect to the direction of light propagation which reflects light propagating through the core to change the direction of light propagation by 90°.
