Abstract: One aspect of the invention relates to a waveguide assembly. The waveguide assembly comprises a waveguide (120) provided on a substrate (126), a waveguide housing (100) and an embedding layer (138) embedding at 5 least part of the waveguide housing (100). The waveguide housing (100) comprises a waveguide channel (102) for guiding the waveguide (120) from the substrate (126) through the embedding layer (138).

Abstract: One aspect of the invention provides a waveguide assembly (250) for providing an interface to a surface module (260). The waveguide assembly comprises an embedded waveguide (204) embedded in a substrate material (224) and a waveguide connector (200) coupled to the embedded waveguide (204). The waveguide connector (200) has a neck portion (202) disposed transverse to the embedded waveguide (204) and a waveguide channel (214) passing though the neck portion (202) forming a channel between the embedded waveguide (204) and the surface (226) of the substrate material (224).

Abstract: One aspect of the intention provides an optical connector arrangement (100). The optical connector arrangement (100) comprises a connector component (114) embedded in a substrate material (130). The embedded connector component (114) includes a fibre optic grating (110) optically coupled to a reflector (116) for directing radiation emitted from the fibre optic grating (110) to a surface (140) of the substrate material (130). The optical connector arrangement (100) also comprises a surface connector component (120) for collecting radiation emitted from the surface (140) of the substrate material (130).

Abstract: One aspect of the invention provides a method for providing a connection between an embedded fibre optic (124) and a surface connector (144). The method comprises providing a substrate (100) comprising an embedded fibre connector component (120), forming a trench (110) to expose the embedded fibre connector component (120), and forming a fibre abutment connection between the embedded fibre connector component (120) and a fibre optic (142). The fibre optic (142) is suitable for guiding radiation between the embedded fibre connector component (120) and the surface connector (144).
