摘要： An optical waveguide 3 comprises a substrate like a Si substrate having a projection with a flat surface and inclined side surfaces thereon, a buffer layer having a refractive index of n.sub.0 formed on lower surfaces of the substrate, a secondary buffer layer having a refractive index of n.sub.0 formed on the buffer layer, a core waveguide having a refractive index of n.sub.1 formed on the secondary buffer layer and a cladding layer having a refractive index of n.sub.0 covering the core waveguide. The flat surface of the projection 31 is exposed through an opening. The secondary buffer layer controls a transmission loss increase caused by partial thickness differences of the ground buffer layer or scattering by scratches or strains created by the grind.

摘要： A plurality of configurations is simultaneously formed in a material by a single laser beam having a desired distribution pattern of wavelengths. An input laser beam has an initial wavelength distribution pattern. The initial wavelength distribution pattern is adjusted or modified into a desired final wavelength distribution pattern. For example, the initial wavelength distribution pattern is a wide range of wavelengths in a single bell-curve distribution while the desired final wavelength distribution pattern has a specific number of sharp peaks each over a predetermined narrow range. The laser beam having the desired final wavelength distribution pattern is focused upon on a material. Because of the multiple peaks in the wavelength distribution, the laser beam is focused at a plurality of the focal distances. A number of structures is simultaneously formed in a material at the multiple focal points or at multiple locations/depths when the above laser beam is projected onto the material.
