Employing finite difference time domain simulations, we demonstrate that electromagnetic field enhancement is substantially greater for tapered optical fibers with plasmonic nanostructures present on their tips as compared with non-tapered optical fibers having those plasmonic nanostructures, or with tapered optical fibers without the plasmonic ...

Tapered microstructure fibers for fiber optical parametric oscillators
2008 Conference on Lasers and Electro-Optics, 2008We present a systematic study of microstructure fibers reduced in size in order to tailor the group-velocity dispersion (GVD). The analysis includes taper recipes, GVD measurements, SEM images, and subsequent fiber optical parametric oscillator performance.

Method of producing tapered optical fiber
Journal of Optical Technology, 2017A novel method for fabricating a subwavelength-diameter optical fiber that can be coupled with optical microresonators is proposed. This method is characterized by the ability to produce a fiber with the specified characteristics required for reliable coupling owing to the possibility of correction of the fiber pulling parameters during fiber ...

Post-shaping optical fiber taper filters
SPIE Proceedings, 2015Geometrical shaping of non-adiabatic single tapers is used to modify the filtering characteristics. The fiber tapers are shaped by successive tapering. The taper shaping produces deeper rejection bands. As an application of the shaped tapers, fluidic temperature sensing cells were fabricated.

Tapered fiber tips for fiber optic biosensors
Optical Engineering, 1995Tapered fiber tips with different geometries are fabricated for developing a fiber optic biosensor. Fluorescence experiments are performed to compare the coupling efficiency of light for different fiber tip configurations. When light is generated in a "thick" layer (> 1 μm) around a fiber core, the continuously tapered tip with the steepest taper ...

Simulation of optical fiber taper shape
2011 2nd International Conference on Photonics, 2011A simplified fiber tapering simulation model is discussed in this paper. Tapering process is solely conducted by constant pulling speed and independent of material properties. Travelling burner tapering system is imitated in the simulation model. The simulation model has a controlling GUI and contained script files that capable to perform taper shape ...

Tapered optical fiber for WDM applications
SPIE Proceedings, 2003This paper investigates the application of a tapered single-mode optical fiber as an optical filter for wavelength division multiplexing applications. The transmission characteristics of the tapered single-mode fibers are studied and observed to be oscillatory due to the non-adiabatically of the tapered region.

Microbubble Generation with Tapered Optical Fibers
Optics in the Life Sciences, 2015We present the microbubble generation using tapered optical fibers. We studied the relation of microbubble generation with experimental parameters. We report the relation of these, with size, speed of growing and lifetime of the microbubbles.

Portable fiber-optic taper coupled optical microscopy platform
SPIE Proceedings, 2017The optical fiber taper coupled with CMOS has advantages of high sensitivity, compact structure and low distortion in the imaging platform. So it is widely used in low light, high speed and X-ray imaging systems. In the meanwhile, the peculiarity of the coupled structure can meet the needs of the demand in microscopy imaging.
