To achieve good coupling efficiency, the spatial mode of the light field has to match the spatial mode of the fiber. In this model, we use the beam envelopes method to compute a small free-space

The paper presents a simulation model developed for a special optical coupler intended for coupling radiation from signal and pump sources used for the realization of cladding- pumped doped fibre
The first lens collimates the light emitted by the fiber, while the second lens focuses the collimated light onto the second fiber tip. The unidirectional formulation is a
Introduction Directional couplers are used for coupling a light wave from one waveguide to another waveguide. By controlling the refractive index in the two waveguides, for instance by heating or
Abstract: The use of grating couplers to couple light near vertically in and out of optical slab or film waveguides represents an attractive method to interface optical fiber to photonic ICs. Newly

The numerical simulations conducted in COMSOL Multiphysics® 6.3 provide a detailed assessment of VCSEL-to-SSMF butt-coupling performance, with a focus on optical coupling efficiency (OCE) and
In this paper, we discuss the principle of coupling an optical signal to an optical resonator. We give the broad outlines of the principle and the experimental parameters then we look at how to optimize this

Optical Fiber: Modes distribution in fiber TE or TM: no E or H field in the propagation direction (like in a waveguide)
A common way to couple light into an optical fiber is to start with a free space beam and use a lens to focus the light onto the fiber end. When a light field enters a fiber, it is decomposed into the set of
In this model, we use the beam envelopes method to compute a small free-space fiber–fiber coupling. The coupling efficiency depends on the position of the coupling lenses.
