Properties of elliptical-core two-mode fiber.
Polarization and modal birefringence of elliptical-core two-mode fibers are investigated. Wavelengths corresponding to zero group delay difference (GDD) between the two spatial modes and between the orthogonal polarizations are computed when the fiber parameters, i.e., the relative core/cladding index difference and the ratio of major over minor axis, are varied. Simple relationships between th...
متن کاملOptical Kerr switch using elliptical-core two-mode fiber.
A new optical-optical switching technique is proposed and demonstrated with a probe-pump scheme, utilizing nonlinear differential phase shift between two spatial modes in a highly elliptical-core fiber. The probe beam is switched from one intensity-lobe position of the fiber output radiation pattern to the other in a 33-m-long fiber at a pump power of 1.6 W.
متن کاملThe Social Bow Tie
Understanding tie strength in social networks, and the factors that influence it, have received much attention in a myriad of disciplines for decades. Several models incorporating indicators of tie strength have been proposed and used to quantify relationships in social networks, and a standard set of structural network metrics have been applied to predominantly online social media sites to pre...
متن کاملApodization of elliptical-core two-mode fiber acousto-optic filter based on acoustic polarization control.
We propose and demonstrate a novel apodization technique for an elliptical-core two-mode fiber acousto-optic filter by twisting the fiber and adjusting the acoustic polarization. The sidelobe suppression in the filter spectrum was improved from -9.7 to -15.5 dB. A theoretical analysis that includes acoustic birefringence explains the experimental results with good agreement.
متن کاملUse of highly elliptical core fibers for two-mode fiber devices.
The four complex, almost degenerate, second-order eigenmodes of a two-mode fiber having a circular core are reduced to two nondegenerate, linearly polarized second-order eigenmodes with stable-intensity lobe positions in a highly elliptical core fiber. Existing two-mode-fiber devices can be improved by this stabilization of the second-order modes. Practical sensors employing the two spatial mod...
