Telecom Optical Amplifiers Can Enhance The Integrity Of Transmitted Data Laser Pointer
Imagine a dim lamp that is not enough to illuminate the room. The laser pointer optical amplifier increases the brightness by increasing the number of photons emitted. Photonics researchers have created such a high-gain optical amplifier, which is compact enough to be placed on a chip. The developed amplifier, when used in optical interconnects, such as transceivers or fiber-optic networks, will help to effectively increase the power of the emitted light before it is exhausted due to optical loss. In addition to potentially replacing the bulky and expensive amplifiers currently used in the research of attosecond science and ultrafast optical information processing, this newly developed nanoscale amplifier also provides an important component for the optical interconnect toolkit, It is possible to provide regenerative amplification for short-distance to long-distance optical interconnection. This work was done in collaboration with researchers from the Institute of Data Storage, Singapore University of Technology and Design, and MIT laser pointer researchers. The details were published in the journal Nature Communications.

We have developed a laser pointer optical amplifier that can amplify 17,000 times at the optical communication wavelength. The assistant professor of Singapore University of Technology and Design who led the development of this amplifier said. We use a proprietary platform called ultra-silicon-rich nitride. Its material composition contains 70% silicon and 30% nitrogen. It has the strong nonlinearity and high photon efficiency required for high gain amplification, which can effectively convert The photons are transferred from the pump light to the signal light. In order to better feel the difference in this scale, the cost of traditional optical parametric amplifiers is as high as hundreds of thousands of dollars and will occupy the space of the entire optical platform. The newly developed laser pointer amplifier is much smaller than a paper clip. The cost is only a small part of the former.
