Claim Text:
1. An optical circuit having a plurality of optical waveguides in an electron definable glass substrate, wherein said electron definable glass substrate is sensitive to irradiation by electrons in an electron beam to effect an increase of optical refractive index in irradiated substrate regions and to facilitate formation of said optical waveguides, said electron definable glass substrate comprises at least the following main constituent components: SiO 2 , Li 2 O, K 2 O, Al 2 O 3 , Na 2 O, ZnO, and Ag 2 O, each of said optical waveguide has a core diameter and a depth of electron diffusion, wherein said core diameter and depth of electron diffusion are controlled by selecting energy of said electrons.
