Abstract:
A hybrid optical waveguide having a linear section and a curved section through which an optical signal of a predetermined wavelength pass, comprising:a planar substrate layer;a lower cladding layer formed on the planar substrate layer of a material having optical transparency in a predetermined range of optical communication wavelengths;a core layer formed on the lower cladding layer where the optical waveguide is formed, the waveguide constituted of the linear section formed of a first optical polymer having a higher refractive index than the lower cladding layer and the curved section formed of a second optical polymer having a higher refractive index than the first optical polymer; andan upper cladding layer formed on the lower cladding layer so as to surround the waveguide core layer, the upper cladding layer formed of a material having a lower refractive index than the first optical polymer.
