Invited - Far-detuned intramodal FWM in optical micro-fiber tunable with the micro-fiber diameter

We report a theoretical and experimental investigation of fardetuned intramodal four wave mixing (FWM) in the fundamental mode of optical microfibers (OMF) depending on their diameter. We demonstrate that the signal wavelength can be tuned over a wide spectral range simply by varying the OMF diameter. Using a pump at 1064 nm, signal wavelengths ranging from around 750 to 950 nm are generating by adjusting the OMF diameter from approximately 8.5 to 6.5 µm.
