Indium Tin Oxide Coated Two-Mode Fiber for Enhanced SPR Sensor in Near-Infrared Region
Published 2017-01-01Get full textA surface plasmon resonance (SPR) sensor based on side-polished two-mode fiber (TMF) coated with indium tin oxide (ITO) film is proposed. ITO enables tuning of resonance wavelength of the sensor through changing its carrier concentration. The advantages of the TMF and ITO are combined in the sensor,...

Measurement of Giant Spin Splitting of Reflected Gaussian Beams
Published 2018-01-01Get full textWe investigate theoretically and experimentally the beam shifts of a Gaussian beam reflected by an air-glass interface at Brewster incidence. For a linearly polarized incident beam, the reflected beam will undergo a spatial spin splitting within the plane of incidence. This spin splitting is up to 8...

Fabrication of rGO-GO Long Period Fiber Grating Using Laser Reduction Method
Published 2017-01-01Get full textA laser-reduction technique is investigated to fabricate a novel long period fiber grating (LPFG), whose period is a section of graphene oxide (GO) and reduced graphene oxide (rGO) films on a side polished fiber. Raman spectra, X-ray diffraction, and Fourier transform infrared spectra show that a CW...
