  • Optical waveguide probe and its manufacturing method
    Patent number: 6370306
    Abstract: The present invention has an object to obtain an optical waveguide probe which is formed in a hook form to illuminate and detect light by a manufacture using a silicon process. This optical waveguide probe is formed in a hook form and structured by an optical waveguide 1 sharpened at a probe needle portion 5 and formed of dielectric and a substrate 2 supporting this optical waveguide 1. This optical waveguide 1 is formed overlying the substrate 2. The optical waveguide 1 is structured by a core 8 to transmit light and a cladding 9 smaller in refractive index than the core 8.
