Claim Text:
1. An optoelectronic structure comprising: a first dielectric layer; a first segment of an optical waveguide on said first dielectric layer; a second dielectric layer on said first dielectric layer and covering said first segment, said second dielectric layer having a bottom surface, a top surface opposite said bottom surface, and a trench extending from said top surface to said first dielectric layer and having a first side and a second side opposite said first side, said first side being adjacent to a first end of said first segment; a second segment of said optical waveguide comprising: a third dielectric layer on said top surface of said second dielectric layer, on said second portion, and within said trench covering said first portion, said first segment and said second segment each having a higher refractive index than said first dielectric layer, said second dielectric layer and said third dielectric layer; said second end of said first portion of said second segment being physically separated from said first end of said first segment and being positioned less than a predetermined distance from said first end of said first segment.
