Dual-Core Nanomechanical Optical Fiber (IMAGE) Optica Caption This image demonstrates the structure of the dual-core nanomechanical optical fiber. Inside the fiber, two cores are shown suspended from above and below. This innovative structure enables the two cores to move and precisely respond to an external mechanical force, moving closer or further apart, depending on data transmission needs.
