A study appeared in the journal Nature Communications about hybrid silicon-polymer modulators that can
The researchers explained that the demand forHigh-speed data transmission has increased dramatically in recent years, and optical communication plays a central role in many necessary data connections. An important component of this is a modulator, which places data on a beam of light passing through an electro-optical material.
Now as an electro-optical material inMost modulators use inorganic semiconductors or crystals, but the advantage of organic polymers is that they can be made with excellent electro-optical properties at a low cost.

Using polymer, the research teamachieved ultra-fast data transfer even at elevated temperatures in a hybrid modulator based on a silicon-polymer modulator. It turned out to be less sensitive to temperature changes than many other models.
In new modulators consisting of severallayers, including polymer and silicon, the incoming laser beam is split into two beams of equal length. Applying an electric field through an electro-optical polymer in one of the sleeves changes the optical properties so that the light wave is slightly displaced. When the two beams reconnect, the speed increases.
So scientists were able to achieve speeds of more than 100 Gbps, while a more complex method using four signal levels could reach speeds of 200 Gbps.
