Ray trajectories in optical fiber tapered sections
Applied Optics, 1978Slab waveguide tapers with finite cladding thickness are analyzed using a geometrical optics approach, and the results are compared with an exact modal analysis. Iteration formulas are derived for the calculation of the propagation angles of the guided modes and the corresponding changes in the core and cladding thicknesses, assuming that the ...

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 ...

Formation and measurement of tapers in optical fibers
Review of Scientific Instruments, 1993A simple fabrication method is described which is capable of producing physically repeatable biconical tapers in optical fibers. A resistively heated platinum wire furnace provides the heat with standard fiber-optic positioning equipment to secure the fiber.

Tapered optical-fiber temperature sensor
Microwave and Optical Technology Letters, 1996Optical power transmission changes of 10–20 dB have been experimentally demonstrated by varying the temperature of a tapered monomode optical fiber that is fixed to a glass plate by two drops of adhesive. The effect arises from different expansion coefficients of the glass substrate and the silica fiber. This induces microbendings in the tapered region.

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 ...

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 ...

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.

Production of Tapered Optical Fibers
2008In this paper, we describe a method for creating tapered optical fibers, reducingthe fiber diameter from 125 fJm to less thanone micron. Optical fibers ore heated and pulled to these sizes at different speeds and lengths,using different flame torches and gases.

Properties and applications of tapered optical fibers
SPIE Proceedings, 2001Unlike conventional optical fibers in cylindrical form, a tapered optical fiber is a fiber with its core diameter linearly varied lengthwise. As a new type optical fiber, it can provide a higher coupling efficiency, converge the energy of output light and improve the stability and flexibility of the system, thus widely usable in the fields of high ...
