compact all fiber optical Faraday components using 65 wt terbium doped fiber with a record verdet constant of 32 rad tm
Optics Express, 2010Co-Authors: Shibin Jiang, John R. MarcianteAbstract:A compact all-fiber Faraday isolator and a Faraday mirror are demonstrated. At the core of each of these components is an all-fiber Faraday Rotator made of a 4-cm-long, 65-wt%-terbium–doped silicate fiber. The effective Verdet constant of the terbium-doped fiber is measured to be –32 rad/(Tm), which is 27 × larger than that of silica fiber. This effective Verdet constant is the largest value measured to date in any fiber and is 83% of the Verdet constant of commercially available crystal used in bulk optics–based isolators. Combining the all-fiber Faraday Rotator with fiber polarizers results in a fully fusion spliced all-fiber isolator whose isolation is measured to be 19 dB. Combining the all-fiber Faraday Rotator with a fiber Bragg grating results in an all-fiber Faraday mirror that rotates the polarization state of the reflected light by 88 ± 4°.

Optical Faraday Rotator Using Ce-Substituted Fibrous YIG Single Crystal Grown by Floating-Zone Method with
1999Co-Authors: Takenori Sekijima, Takashi Fujii, Kikuo Wakino, Masakatsu OkadaAbstract:A new optical Faraday Rotator using a fibrous Ce-substituted yttrium-iron-garnet (Ce:YIG) single crystal was developed. The fibrous Ce:YIG single crystal was successfully grown by the floating-zone method with infrared-assisted YAG laser heating at a fast growth rate. This crystal has a good quality and shows a better figure-of-merit for an optical Faraday Rotator at wavelength m compared with commonly used Bi-substituted YIG films. Ce:YIG single crystals grown by our method are expected to reduce the cost of optical isolators.

A polarization-stable Er-doped superfluorescent fiber source including a Faraday Rotator mirror
IEEE Photonics Technology Letters, 2000Co-Authors: D.g. Falquier, M.j.f. Digonnet, H.j. ShawAbstract:We report a tenfold stability improvement in the mean wavelength variations induced by polarization fluctuations in an Er-doped superfluorescent fiber source. This was accomplished by replacing the mirror in a double-pass source with a Faraday Rotator mirror, thereby nearly eliminating polarization dependent gain. The resulting mean wavelength variations of less than 3.5 parts-per-million (limited by the detection noise floor), approach the requirement for inertial-grade fiber optic gyroscopes.

improved polarization stability of the output mean wavelength in an er doped superfluorescent fiber source incorporating a Faraday Rotator mirror
Optical Fiber Communication Conference, 1999Co-Authors: D.g. Falquier, M.j.f. Digonnet, H.j. ShawAbstract:Erbium-doped superfluorescent fiber sources (SFS) in the standard forward, backward, and double-pass configurations exhibit significant dependencies of the output mean wavelength on the pump state of polarization. This is due largely to polarization-dependent gain (PDG) and gives rise to long-term drifts of the source output mean wavelength through changes in the fiber birefringence. By replacing the mirror in a double- pass source with a Faraday Rotator mirror (FRM), the magnitude of the SFS mean wavelength variations due to pump polarization changes is reduced by a factor of 5 - 40, depending on source design parameters. Simulation results as well as experimental demonstration of the Faraday double-pass SFS are discussed in this paper. We measured 10 parts per million for the polarization-related mean-wavelength variations in this source, approaching the requirement for high-accuracy fiber gyros.
