The patent application (Publication Number: US20240036264A1) describes an optical switch for optical signals that includes a plurality of optical fibers arranged in an array along an optical axis, each fiber having a fiber tip. The switch also features a biconvex lens with front and back convex surfaces, and a microelectromechanical (MEMS) mirror that can be selectively oriented to reflect the optical signals. The optical switch is designed to conduct optical signals efficiently and direct them from input fibers to selected output fibers.

Furthermore, the optical switch includes a fiber head holding the optical fibers in the array, with the fiber tips exposed at an interface surface. The housing encloses the fiber head, biconvex lens, and MEMS mirror, ensuring the components are protected and aligned correctly. The patent application also details the use of a two-dimensional array of optical fibers, a biconvex lens made of specific optical materials, and a method for conducting and reflecting optical signals within the switch. Overall, the patent application outlines a novel optical switch design that aims to improve the efficiency and precision of optical signal transmission in a compact and controllable manner.
