Here, we demonstrate the propagation through bent waveguides with different bending radii. The thickness of all waveguides are same and let’s denote as “d” here. Then we have 3 cases where the radius of bending is d, 2d or 3d. With the smaller radius, the leakage from the bending is stronger compared to the other ones.
Bent waveguides are a type of optical waveguide that are used to guide and direct light along a specific path. These waveguides are typically made of a high refractive index material, such as glass or silicon, and are designed to have a specific curvature in order to bend and redirect the light.
One common use case for bent waveguides is in optical fiber communications, where they are used to direct light signals along a specific path through a network of fibers. This allows for the efficient and high-speed transmission of data over long distances.
Bent waveguides are also used in other applications, such as in spectrometers for analyzing the composition of materials, in medical imaging devices for producing high-resolution images of the human body, and in optical sensors for detecting and measuring various physical properties.
