Customization Process for Energy-Saving Optical Directional Couplers for Rail Transit

In this paper, we present the design, fabrication and characterization of a traveling wave directional coupler modulator based on electro-optic polymer, which is able to provide high linearity, high speed, and low optical insertion loss. Directional couplers are a fundamental building block in integrated photonics, particularly in quantum applications and optimization-based design where precision is critical. Accurate functionality is crucial to ensure reliable operation within classical and quantum circuits. Based on Finite Difference Eigenmode, Finite-Difference Time-Domain simulations, and experimental measurements.

Method for fabricating fiber optic couplers

Method for fabricating fiber optic couplers

A method for the fabrication of a fiber optic coupler includes a step of fusing together two optical fibers along their longitudinal sections by heating them and a step of stretching the two optical fibers independently of one another with different conditions of tension and/or. It functions by dividing a single incoming light path into multiple outgoing paths, or by combining light from several input paths into a single output fiber. 2-photon lithography enables custom fabrication of optical waveguides at a sub-micron resolution and millimeter scale. Custom optical fiber architecture is a powerful component for development of fiber coupler systems and advancement of fiber based imaging technology.
