Wavelength and Temperature Performance of Polarization Transforming Fiber
Allen Rose, N. Feat, Shelley M. Etzel
We have theoretically and experimentally investigated an optical fiber with circular eigenmodes on one end and linear polarization modes on the other end. We call this fiber a polarization-transforming fiber because the local modes, or polarization states they represent, are converted from linear to circular, and vice versa, in the fiber. We have developed and implemented a post-draw process for making the polarization-transforming fiber making fiber samples 30 mm long with losses less than 1 dB and a polarization-mode conversion from circular to linear greater than 20 dB. Also, we have modeled and measured the dependence on wavelength and temperature of polarization-transforming fiber samples. The measured normalized wavelength dependence of a sample fiber 30 mm long was about 1.4 × 10-4 nm1, and the measured normalized temperature dependence was approximately 6 × 104 ° C1. These values are better in some cases than values for conventional high-birefringent fiber quarter-wave plates.
