Journal ArticleDOI
All-fiber acousto-optic frequency shifter
TL;DR: An all-fiber-optic frequency shifter is demonstrated that uses mode coupling between the LP(01) and LP(11) modes by a traveling acoustic flexural wave guided along the optical fiber.
Journal ArticleDOI
Use of highly elliptical core fibers for two-mode fiber devices.
TL;DR: 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-orders with stable-intensity lobe positions in a highly elliptical core fiber.

Apparatus using two-mode optical waveguide with non-circular core
Byoung Yoon Kim,James N. Blake +1 more
TL;DR: In this article, a two-mode optical waveguide with a non-circular core is used to provide stable spatial intensity patterns in both propagation modes for light propagating therein.
Journal ArticleDOI
Propagation and optical interaction of guided acoustic waves in two-mode optical fibers
TL;DR: In this paper, a review of the properties of several mode groups is given, and computed results are shown for a wide range of material properties, including dispersion relations, mode patterns, power relations, and acousto-optic coupling strength.
Journal ArticleDOI
Perturbation effects on mode propagation in highly elliptical core two-mode fibers
TL;DR: In this article, the propagation of both fundamental and second-order modes in highly elliptical core two-mode fibers under external perturbations is investigated, including axial strain, radial strain, hydrostatic strain, temperature change, twisting, squeezing, and bending.
