Claim of US Patent No. 9,791,640

1. An interposer for coupling an optical conduit to an optical component, said interposer comprising:
an optical component comprising at least a photonic integrated circuit having an optical waveguide;
a first lens component having a first lens overlaying said optical component, wherein said optical component and said first
lens component are discrete components;

a second lens component overlaying said first lens component and having a second lens, said first and second lenses being
configured to define an expanded-beam coupling therebetween;

wherein said first and second lenses are integral with said first and second lens components, respectively;
wherein an air gap exists between said first and second lenses;
wherein said first and second lenses are configured as collimating lenses;
at least one reflective surface optically coupled with said second lens;
a first optical path at least partially defined between said optical component and said first lens to accommodate a diverging
light beam from said optical component to said first lens, said first optical path being essentially perpendicular to said
optical waveguide;

a second optical path at least partially defined between said second lens and said at least one reflective surface to accommodate
a converging light beam from said second lens to said at least one reflective surface; and

a separable interface between said first and second lens components at said expanded-beam coupling.
