Vibration-Immune Metrology Drives Optical Communications

SWIR interferometers support the current drive toward optical communications in the 1535–1565nm wavelength band.

To keep pace with the growth of data-heavy applications, government and space agencies are investing heavily in free space laser communications. Using multiple wavelengths, laser sources can increase data transfer rates far beyond the capabilities of radio-frequency (RF) communications. But developing those data links requires optics that push the capabilities of today’s manufacturing techniques—and the metrology to verify them.
