Benefits of technology

This new type of lightweight optical component called an optofluidic device (OP) can be used for controllably shaping electromagnetic waves based on their properties such as phase or frequency differences caused by changes made along certain parts of it's structure. These devices have improved performance compared to traditional components like lenses that are bulky due to its material composition.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the performance of optofluidic components used for communication purposes due to their ability to efficiently transmit signals over long distances without being affected from external influences like vibrations caused by environmental factors like temperature variations.

Abstract

The invention discloses a T-shaped photonic crystal power divider, which belongs to the technical field of materials, and relates to application technology of photonic crystals. In the invention, based on the prior T-shaped photonic crystal power divider, one dielectric cylinder is added in the intersection of a vertical line defect and a horizontal line defect of a T-shaped line defect, and two dielectric cylinders most close to the added dielectric cylinder in the vertex position of two right-angle corners of the T-shaped line defect are removed respectively at the same time. Other dielectric cylinders can also be respectively added in the positions twice of a crystal cycle length which is constant a, from the added dielectric cylinder on the left side, the right side and the lower side, and three dielectric cylinders most close to the intersection of the vertical line defect and the horizontal line defect at the two right-angle corners of the T-shaped line defect are removed respectively at the same time. The improved T-shaped photonic crystal power divider has the advantages of high amplitude-frequency characteristic flatness in a pass band, reduction of interaction between two output ends of the T-shaped power divider and better practicability.
