A METHOD OF FORMING AN OPTICAL DEVICE BY LASER SCANNING |
摘要 |
A method of forming an optical device in a body (32), comprises performing a plurality of laser scans (34,36) 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 (34a, 34b 34f; 36a, 36b 36f) 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. |
