Estimation of coupling power parameter of fused coupled fibers
SPIE Proceedings, 2008Fiber couplers are widely used in telecommunications and industry as passive splitting power devices. The effective power coupling and transmission from one fiber to another is mainly determined by both the coupling length and the coupling coefficient.

Fiber To Fiber Coupling In A Multichannel Sensor System
SPIE Proceedings, 1988An electromechanical optical scanner is described, which, allows the sequential coupling. of a single to 19 multimode optical fibers. In order to achieve a good. coupling efficiency between the fibers, quarter pitch graded index microlenses (GRIN) are used.

Fiber-coupled multiplexed confocal microscope
Optics Letters, 2000We describe a new parallel scanning mechanism for confocal microscopy that is inherently fiber-optic compatible and that retains the simplicity of the line scanning confocal microscope. The method works by employing an incoherent fiber-optic bundle that maps a line illumination pattern back on itself on double passing, while separating the fibers that ...

The passive devices presented so far are based on single-mode high index-contrast (HIC) wave-guiding which enables the dense integration of many such devices on a photonic integrated circuit (PIC). A major disadvantage of this approach, compared with more conventional low index-contrast (such as silica based) integrated optics, is the difficulty of ...

Dynamics of solitons in coupled optical fibers
Optics Letters, 1989The dynamics of soliton interaction in two tunnel-coupled optical fibers as a function of their phase difference Psi is analytically and numerically investigated. It is shown that if Psi = 0 or pi, no energy redistribution occurs in the fibers, and the soliton pulses either form a coupled state (Psi = pi) or repulse each other and separate during ...

Coupling in Optical Fibers: A Review
2025 European Conference on Optical Communications (ECOC)Mode coupling is a fundamental concept to model and understand light propagation in optical fibers when they are affected by irregularities with respect to an ideal case. This paper reviews the basic principles of coupled mode theory and its main applications.

Mode Coupling in Optical Fibers
Optical Fiber Communication Conference (OFC) 2024Mode coupling plays a crucial role in spatial-division-multiplexed transmission systems. This paper review and explores new approaches to modelling and characterization of mode coupling in multicore and multimode fibers.

Wedge coupling of lasers into multimode fibers
Applied Optics, 1983Design and experimental data for obtuse-angled wedges used in coupled configurations of diode lasers and multimode fibers are presented. An analytic definition of the connection between the wedge angle and the fiber acceptance half-angle is developed, along with a formula for the minimum half-angle.

In modern optical communication systems, it is of the highest importance to transmit as much optical power from the transmitter to the receiver. It seems that future systems will not be that strongly dependent on good optical waveguides . Actually, even after 25 years of existence of low-loss glass fibers , the coupling efficiency remains the biggest ...

Fiber mode coupling in transmissive and reflective tilted fiber gratings
Applied Optics, 2000Whereas core-mode reflection and core-mode-to-radiation-mode coupling in tilted fiber Bragg gratings is well understood, as is coupling between a core mode and higher-order core and cladding modes in untilted gratings, here we analyze in detail the coupling among core modes and cladding modes in reflective and transmissive tilted fiber gratings.
