Abstract:
1. An optical circuit configured to input and output an optical signal to and from a space, the optical circuit comprising a planar lightwave circuit (PLC) comprising a substrate, a cladding layer formed on the substrate, and at least one optical waveguide core formed in the cladding layer, the optical circuit further comprising: an angled polished facet through which the at least one optical waveguide core inputs and outputs the optical signal to and from the space; a reinforcement part positioned above a surface of the substrate of the PLC and near the aperture, the reinforcement part having a facet aligned with and extending from the angled polished facet so that the facet of the reinforcement part and the angled polished facet form an extended angled facet, a lens which is bonded onto the extended angled facet, and which collimates or condenses an optical signal from an aperture or to an aperture of the at least one optical waveguide core; and an adhesive layer positioned between the extended angled facet and a bonded face of the lens; and wherein
