AI Technical Summary

Technical Problem

Traditional rectangular-channel erbium-ytterbium co-doped nanoparticle polymer optical solids and polymer device mass structures of erbium-ytterbium co-doped optical waveguide amplifiers increase in size and occupy a large wafer area as the length of the amplification region increases, making it difficult to meet the high integration requirements of on-chip integration.

Method used

The erbium-ytterbium co-doped polymer waveguide optical amplifier with Bragg grating structure enables signal light to travel back and forth in the gain region by setting Bragg gratings at both ends of the optical waveguide, thereby increasing the length of the amplification region and achieving high gain performance on a small chip.

Benefits of technology

A high-gain optical waveguide amplifier on a small-sized chip has been realized, which features simple process, low cost, high integration with silicon-based optical devices, and high gain per unit length, resulting in a significant improvement in gain performance.
