An optical apparatus () for routing an optical signal () comprises a body () comprising a material. A waveguide () is formed in the body () by laser modification of the material. The optical apparatus () further comprises a region () comprising a lower refractive index than the material of the body () and defines an interface () between the region () and the waveguide (). The waveguide () and the interface () are aligned relative to each other for routing the optical signal () therebetween and reflecting the optical signal () at the interface ().

Optical apparatus, optical assembly and methods of manufacture thereof

Optical apparatus and methods of manufacture thereof An optical apparatus () for evanescently coupling an optical signal across an (interface () is described. The optical apparatus () comprises a first substrate () and a second substrate (). The optical signal is evanescently coupled between a first waveguide () formed by laser inscription of the first substrate () and a second waveguide () of the second substrate (). The first waveguide () comprises a curved section () configured to provide evanescent coupling of the optical signal between the first and second waveguides () via the interface ().

Optical apparatus and methods of manufacture thereof

A method of forming an optical device in a body (), comprises performing a plurality of laser scans () to form the optical device, each scan comprising relative movement of a laser beam and the body thereby to scan the laser beam along a respective path () through the body to alter the refractive index of material of that path, wherein the paths are arranged to provide in combination a route for propagation of light through the optical device in operation that is larger in a direction substantially perpendicular to the route for propagation of light than any one of the paths individually.
