Abstract
An elliptical-core (e-core), two-mode fiber optic micro-device for in-line modulating and switching has been studied. The polished surface is so close to the core of the fiber that the differential propagation constant between the LP01 and LP11 even modes is strongly dependent on the refractive index of the deposited oil. The power from a single lobe and the total power are separately received by two detectors. In experiments, the dependence of the differential phase shift between the two modes on the refractive index of the deposited material was observed. The switching characteristics of the structure so fabricated, switching between the two lobes were also demonstrated. Further, different coupling characteristics of the two modes propagating the fiber into the deposited layer, which functions as a planar waveguide, have been observed.
