Abstract
An optical interface device for optically connecting photonic devices to optical device along with methods of making. The method includes providing a glass support member that is either monolithic or laminated. A laser beam is used to write cores in the body of the support member. The support member includes a bend section and the cores generally follow the bend section and serve to define curved optical waveguides. The cores provide strong out-of-plane optical confinement, thereby allowing for strong bends and therefore a compact design for the optical interface device.
