AI Technical Summary

Problems solved by technology

[0003] However, the biggest disadvantages of organic polymer waveguides applied to integrated optical devices are their uneven stress, poor stability, low lifetime, and high-quality polymer materials are expensive, which greatly limits their commercial application in the field of optical communication.

Most of the current polymer waveguides are single-clad, and the stress of the single-clad flexible waveguide is not uniform, which will cause large loss and dispersion problems.
