Abstract: A rib waveguide structure comprising a layer (4) of light conductive material defined between two planar faces with a rib (9) formed on one of the faces and an optical components e.g. a tapered waveguide (6) optically coupled to the other face. An inverted rib waveguide comprising a light conductive layer (11) and a rib (10) that projects from the light conductive layer (11) into a substrate (4, 8) is also described as well as other optical devices comprising a light conductive layer separated from a substrate by a non-planar layer (3) of light confining material and optical devices comprising two or more layers (2, 3; 18, 19, 20) of light confining material buried within a rib with a light conducting component (10; 17; 22) at least a part of which is formed between planes defined by the two layers of light confining material. A method of forming such devices is also described.

Abstract: A method of producing an optical grating component including only a single continuous grating field formed in a longitudinal waveguide rib, the method including the steps of defining a grating in an optic chip including a portion thereof through which the longitudinal waveguide rib is to extend, and then defining the lateral edges of the longitudinal rib in the optic chip, whereby any portion of the grating extending laterally beyond the lateral width of the rib is removed in the step of defining the lateral edges of the rib leaving a single continuous grating field that has straight lateral grating boundaries that are laterally aligned with the straight lateral edges of the rib.

Abstract: An arrangement of an integrated optical waveguide (1) relative to a V-groove (2) for receiving an optical fibre (5) which is to be optically coupled with an end of the waveguide (1) is described. A waveguide (1) is formed in a crystalline optical substrate (3), and a V-groove (2) formed therein beneath an elongate parallel sided window in the substrate with a centre line (2A) of the V-groove (2) aligned with an end (1A) of the waveguide (1). The parallel sides (2B, 2C) of the window at the end of the V-groove (2) aligned with the waveguide (1) terminate out of alignment with each other in a direction along the length of the V-groove whereby the V-groove undercuts a portion (3A) of the optically conducting layer (3) beneath said end of the waveguide (1). The end of the waveguide (1) therefore overhangs the end of the V-groove (2) to enable the end of an optical fibre (5) to be located in close proximity thereto.
