Abstract

Spiral morphology-dependent resonances have been observed in a tilted optical fiber. The polarization-preserving and the cross-polarized elastic-scattering spectra for plane-wave illumination show that the wavelengths of the resonances are blueshifted quadratically as the fiber tilt angle increases. When a focused Gaussian beam illuminates the fiber at its edge, the resonances are blueshifted and broadened as the detector is offset from the scattering plane with the maximum scattering intensity. The blueshift with focused beam illumination is also a consequence of the spiral resonances.

Internal spiral wave of a tilted optical fiber with respect to the laboratory reference frame. The phase-matching condition between the spiral mode and the external incident wave reduces the effective cavity length for the spiral wave by a distance d/n, where n is the fiber refractive index.

Elastic-scattering spectra detected at a 90° scattering angle from a tilted fiber that is illuminated by an unfocused beam. The tilt angle is θ. (a) Both the incident and the scattered light were horizontally polarized (TE–TE). (b) Blueshift of the a, b, and c MDR’s with θ2 dependence.

Fig. 3

Elastic-scattering spectra of a perpendicularly incident θ=0° focused Gaussian beam at the fiber edge. (a) TM–TM spectra detected at 120° scattering angle. The three spectra were measured with the detector at the maximum scattering intensity (0  mm) and with the detector height offset by 2 and 4  mm. The f peaks in the three spectra are normalized. The d, e, and f MDR’s were broadened and slightly blueshifted as the detector-height offset increased. (b) TE–TE and TE–TM spectra measured at 0-mm height offset. The TE–TM spectrum shows a wavelength shift and is 0.5% of the TE–TE intensity.
