Abstract: A substrate (1;101;201) for an optical chip (10;110;210) has a surface (3;103;203) in which a channel (7;107;207) is provided for an optical fibre (13;113) to be received in. To aid in drawing off any excess adhesive used in securing the optical fibre in the channel, the channel is provided with a bottom (23,25;123,125;223,225) having a stepped profile. To accommodate flaring of the free end (14;114;214) of the optical fibre, e.g. caused by laser cleaving, the channel may step into an enlarged section at an end face (12;112;212) thereof. These features promote a flatter lie of the optical fibre in the channel and improved optical coupling between the optical fibre and an optical component (5;105;205) on the surface at the end face. For optimal optical coupling between the optical fibre and the optical component, the end face may extend widthwise at an inclined angle to the axis of the channel, which angle substantially corresponds to the cleave angle of the free end of the optical fibre. To prevent the free end of the optical fibre impacting the optical component on feeding of the optical fibre along the channel, a recess (27;127;227) may be provided in the end face to space the free end from the optical component.
