All-fiber optical frequency shifter

A new type of all-fiber frequency shifter is demonstrated. It is capable of operation at lower frequencies than traditional approaches based on surface acoustic waves and is believed to be unique in not requiring the removal of the fiber buffer coat.

Zusammenfassung:A new type of all-fiber frequency shifter is demonstrated. It is capable of operation at lower frequencies than traditional approaches based on surface acoustic waves and is believed to be unique in not requiring the removal of the fiber buffer coat. For 2.3-W electrical drive the prototype achieved a 2.5% conversion efficiency and greater than 20-dB unwanted sideband suppression.
