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.

The present disclosure provides a method for manufacturing an aspherical prism and an aspherical prism. The method includes step S1, forming a prism and a lens into one piece to obtain a forming body glass by using a hot-pressing molding; step S2, adhering the forming body glass to a tooling, and performing a right-angle surface milling on the forming body glass according to a preset size while reserving a processing amount for a polishing process; step S3, adhering the forming body glass formed after the right-angle surface milling to an optical backing plate for polishing; step S4, cutting the forming body glass formed after the polishing; step S5, coating the forming body glass formed after the cutting; and step S6, inking the forming body glass formed after the coating. The method can improve the structural precision and processing efficiency of the aspherical prism.

A method of reforming glass includes placing a glass sheet on a mold having a shaping surface for forming the glass sheet into a shaped glass article. A target starting mold forming temperature and temperature window are selected for the mold. A target starting mold forming temperature and temperature window are also selected for the glass sheet. The glass sheet and mold are simultaneously exposed to a first furnace condition controlled to a furnace temperature set point above the target starting mold forming temperature until a temperature of the mold is within the first temperature window. The glass sheet and mold are simultaneously exposed to a second furnace condition controlled to a furnace temperature set point between the target starting mold forming temperature and first furnace temperature set point until a temperature of the glass sheet is within the second temperature window, after which forming of the glass sheet starts.

Techniques for making glass components for electronic devices are disclosed. The techniques disclosed herein can be used to modify a glass workpiece to form a three-dimensional glass component, such as a glass cover member. The techniques may involve reshaping the glass workpiece, fusing glass layers of the workpiece, or combinations of these. Glass components and electronic devices including these components are also disclosed.

A method of fabricating strengthened glass includes strengthening a glass substrate to form a strengthened glass substrate including a first surface and a second surface opposite to the first surface, and slimming the strengthened glass substrate. The slimming may include slimming the first surface and not slimming the second surface, or slimming the first surface and the second surface differently from each other. Strengthened glass fabricated by this method of fabricating strengthened glass may be used in a bent display device.
