Claim 14:
15. The photonic integrated circuit of claim 1,
further comprising:
a second intermetal dielectric level on the upper metal layer on a side opposite the intermetal dielectric layer;
a third metal layer on the second intermetal dielectric level on a side opposite the upper metal layer; and
one or more second optical waveguide levels within the second intermetal dielectric level, each second optical waveguide level including one or more second level optical waveguides formed therein, each of the one or more second optical waveguide levels having corresponding top and bottom faces;

wherein:
a top face of an uppermost second optical waveguide level of the one or more second optical waveguide levels is a distance D5 from the third metal layer;
a bottom face of a lowermost second optical waveguide level of the one or more second optical waveguide levels is a distance D6 from the upper metal layer; and
D5 and D6 are both at least 600 nm but not more than 1200 nm.
