Abstract
Abstract An optical electronic component, in which strip waveguides of limited depth and lateral width are formed in undoped dielectric substrate, e.g. an undoped crystal, by implantation of rare-earth ions or ions of transition metals, preferably laser-active ions with energies of 50 keV to 10 MeV.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
101 words
An optical component comprising: a body of a dielectric optical component substrate having a surface delimited by lateral edges and longitudinally spaced ends, said substrate being continuous between said ends; and a strip waveguide formed at said surface by rare-earth ions or ions of a transition metal implanted in said substrate as doping elements in a generally elongate pattern over a region of said surface spaced inwardly from said lateral edges and localized to only a limited portion of the full cross section of said body, said region being continuous with said body over an entire length of said strip waveguide.
Claim 2
Dependent Claim
101 words
An optical component comprising: a body of a dielectric optical component substrate having a surface delimited by lateral edges and longitudinally spaced ends, said substrate being continuous between said ends; and a strip waveguide formed at said surface by rare-earth ions or ions of a transition metal implanted in said substrate as doping elements in a generally elongate pattern over a region of said surface spaced inwardly from said lateral edges and localized to only a limited portion of the full cross section of said body, said region being continuous with said body over an entire length of said strip waveguide.
Claim 3
Dependent Claim
80 words
The optical component defined in claim 1 wherein said substrate is formed at said surface with a plurality of mutually spaced apart laterally limited regions thereof spaced inwardly from said lateral edges and doped in respective elongate patterns with said rare-earth ions or ions of a transition metal as doping elements, thereby forming respective spaced apart strip light waveguides in said substrate, each of said regions being continuous with said body over an entire length of the respective strip waveguide.
Claim 4
Dependent Claim
21 words
The optical component defined in claim 2 wherein said regions have different ones of said ions implanted therein as doping elements.
