Publication number: 20230387650Abstract: An LBM package and method for packaging an LBM using a stamped metallic mirror array that folds light beams, correct beam shapes, fold and/or redirect beam propagations. The mirror array can be integrated or assembled inside an LBM to provide beam shaping and redirection of the high-power beams near the laser diode. The LBM incorporates a stamped metallic freeform mirror or reflector with an off-axis parabolic shape is configured to fold and collimate laser beam. A precision stamping process is deployed to produce an array of miniature, freeform mirrors in high volume applications. The mirror array simplifies the optical path and eliminates passive components such as refractive lenses and dichroic filters that combine RGB beams. Stamped metallic optical components with micro-scale freeform mirrors in the LBM are tolerant of high temperatures and can thermally diffuse heat away from the reflective surface for high power applications.Type: ApplicationFiled: April 17, 2023Publication date: November 30, 2023Inventors: Yang CHEN, Robert Ryan VALLANCE, King-Fu HII

Patent number: 10739535Abstract: A process and tool for reshaping and resizing grooves that were pre-formed in a pair of ferrules halves of an optical fiber ferrule. The pre-formed grooves are further subject to a separate, subsequent reshaping and resizing step using the tool and a gauge that may be a bare section of optical fiber or a pin. The ferrule halves are aligned, and using the pre-formed grooves as guides for the gauge optical fiber or gauge pin, the ferrule halves are compressed together with the gauge optical fiber or gauge pin therebetween, thereby reshaping and resizing the respective grooves on the ferrule halves. After reshaping and resizing, the resultant groove that is finally formed on each ferrule halve would be precisely shaped, sized and located with respect to the external alignment surface of each ferrule halve. The ferrule halves may be used to terminate an optical fiber cable.Type: GrantFiled: September 6, 2017Date of Patent: August 11, 2020Assignee: CUDOQUANTA FLORIDA, INC.Inventors: Robert Ryan Vallance, King-Fu Hii, Yang Chen, Joseph Kim Bond, Po-Tsung Wu, Michael K.
