Applications:

Quantum communication and quantum key distribution
Quantum communication and quantum key distribution are encrypted communication technologies based on the principles of quantum mechanics and are designed to provide higher security and confidentiality. In quantum communication, light with a wavelength of 1270nm is widely used for quantum channel transmission.
Since the transmission attenuation of light with a wavelength of 1270nm in optical fibers is small, longer distance quantum communication transmission can be achieved. In addition, compared with other wavelengths, the control and detection technology of 1270nm wavelength light is also relatively mature, which can provide higher transmission efficiency and lower bit error rate.

Biomedical applications
Light with a wavelength of 1270nm has extensive research and application value in biomedical applications. Light of this wavelength has a certain correlation with the absorption of water molecules in human tissue, so it is used in tissue imaging and laser therapy.
For example, 1270nm wavelength laser can be used to accurately locate and treat skin lesions, vascular lesions, and eye diseases. In addition, in the field of optical coherence tomography (OCT), light with a wavelength of 1270nm is also used for high-resolution ophthalmic image acquisition.
