Patent ID: 7474826

Claim:
A mounting arrangement for at least one optical component in a planar lightwave circuit, the arrangement comprising: a substrate, an input optical fiber mounted on said substrate, an output optical waveguide in a given set of planar layers of said substrate, said one optical component is mounted on said substrate to transmit optical radiation from said input optical fiber to said output optical waveguide, and a further optical waveguide is disposed on said substrate in the same planar layers of said output optical waveguide wherein said output optical waveguide and said further optical waveguide are aligned along an input-to-output propagation path, thereby providing substantial alignment of said output optical waveguide and said further optical waveguide, said further optical waveguide is interposed between said input optical fiber and said optical component and wherein said optical component is interposed between said further optical waveguide and said output optical waveguide, and wherein respective end surfaces of said output optical waveguide and said further optical waveguide are offset with respect to a perpendicular to said input-to-output propagation path, and a propagation path of radiation through said at least one optical component is at an angle with respect to said input-to-output propagation path.
