Thorlabs' SM300 fiber consists of an undoped, pure silica core surrounded by a depressed, fluorine-doped cladding. Since these fibers do not contain germania (GeO2), which causes electronic defects and color centers associated with the Ge-O bond, the primary cause of photodarkening is greatly reduced. As a result, power handling in the blue region is increased from several milliwats to several watts. The transmission-limiting effects caused by other nonlinearities (e.g., stimulated scattering) or even thermal damage are also increased over those of a conventional silica fiber doped with germanium. In the UV region, the SM300 will still exhibit some photodarkening, but will have superior performance compared to conventional fibers.

I would like to know the dispersion of this fiber at around 400 nm. Can you pleas let me know this value? Thanks! Gleb

Response from Jeremy at Thorlabs: Based on the generally used formula for waveguide dispersion and chromatic dispersion, the estimated dispersion for SM300 is on the order of -23 ps/(km-nm) at 400nm. That value can change depending on the actual numerical aperture and the cut-off wavelength of each spool of fiber.

Response from Tim at Thorlabs: Thank you for your feedback. The S405-HP has a core index of 1.46958 and clad index of 1.46428 measured at 405nm. The MFD @ 460nm is 3.2 +/- .5 um. Please use these as references but note that they are approximate and may vary from lot to lot.

Dear Sir Or Madame, Recently, we purchased the S405-HP fiber. We need to know the cladding and core refractive indices as well as the core radius at 473nm that I cannot find in specs. I thank you in advance for your answer and assistance. Best regards, Marko

Response from Buki: Thank you for your feedback Michael. For the 460HP fiber, at 532nm, the cladding refractive index is about 1.461, and the core refractive index is about 1.467. For the S460-HP, at 633nm, the core refractive index is about 1.46873 and the cladding refractive index is about 1.46298.

I need to know the cladding refractive index (at ~550nm or some nearby wavelength) for the 460HP and S460-HP fibers. This doesnt seem to be given in the spec sheets.

Response from Buki. For single mode fiber, a flat cleave would provide a good optical surface that makes it unnecessary for the end to be polished. We have two products for fiber cleaving: XL411 and S90W.

I recently bought some optical fiber (460hp) from you guys and was wondering how to polish the ends. My application does not require a connector but it seems the polishing kits do. Can you Help?

A response from Adam at Thorlabs to fahd: We have three methods for stripping this type of fiber. The first is using a mechanical stripper, which would not work for your application. The next two might: Method 2: Chemical Dip in solvent for a few minutes. Jackets will absorb the solvent and swell up. Grab fiber between thumb and index finger (with some tissue in between) and rub swollen portion off. Method 3: Hot Sulfuric Acid Hot sulfuric acid (T=150-180°C). Dip a few minutes or until all acrylate is dissolved. Rinse in clean water after excess acid is drained off. Then, rinse in acetone, then isopropyl alcohol and blow dry. I will email directly with more information about method 2.

CCC1310-J9, SM1250G80, and SM1500G080 Bend Loss Information

The CCC1310-J9 fiber is designed to have similar characteristics to SMF-28e+, with the advantage of enhanced bend insensitivity. The table to the right shows complete macrobend loss specifications for CCC1310-J9 for different mandrel radii, and the table below shows a comparison between CCC1310-J9 and SMF-28e+.

The SM1250G80 and SM1500G80 offer a smaller cladding size (80 µm vs. 125 µm), which offers an even lower bend loss. When bent, an 80 µm fiber suffers approximately 40% lower stress than standard 125 µm cladding fibers.

Below Left: Using a source outputting at 1996 nm and a Ø30 mm mandrel, the bend losses (dB) of the SM2000 and SMF28 fibers were measured for each turn of the fiber around the mandrel. Based on the measurement, the loss/turn of the SM2000 fiber is ~0.08 dB. For the SMF28 fiber, the loss/turn is ~3 dB. The SM2000 fiber is much less sensitive to bending than SMF-28e fiber.

Below Right: Power as a function of distance is shown. The measurements were obtained by starting with 150 m of SM2000 fiber and measuring power output after a series of cut backs. For this measurement 1996 nm input light was used.
