Overlap relation between free-space Laguerre Gaussian modes and step-index fiber modes.

چکیده
We investigated the overlap relation of the free-space Laguerre-Gaussian modes to the corresponding linearly polarized modes of a step-index fiber. To maximize the overlap for an efficient coupling of the free-space modes into a fiber, the scale-dependent overlap was theoretically and experimentally determined. The presented studies pave the way for further improvement of free-space to fiber optical connections.

Wigner representation of Laguerre--Gaussian beams.
A phase-space description of the Laguerre-Gaussian modes is presented that points out the connection between these modes and the Hermite-Gaussian modes. We exploit the underlying phase-space symmetries to derive a closed-form expression for the Wigner distribution function of Laguerre-Gaussian modes. This expression is as compact as the one for the Hermite-Gaussian modes.
متن کاملGeneration of Laguerre–Gaussian modes in fiber-coupled laser diode end-pumped lasers
A technique has been developed for the generation of Laguerre–Gaussian (LG0,l) modes in a fiber-coupled laser diode end-pumped microchip laser. A theoretical model is also developed to predict how the oscillation of LG0,l modes is affected by the pump position, the pump size and the cavity mode size. With a 1-W fiber-coupled diode, the highest-order LG0,l mode that can be generated is l = 23.
متن کاملLaguerre-Gaussian mode division multiplexing in multimode fiber using SLMs in VCSEL arrays
Mode division multiplexing (MDM) is a promising technology for increasing the aggregate bandwidth of multimode fiber (MMF) in conjunction with wavelength division multiplexing (WDM) in face of the impending capacity crunch in optical fiber networks. This paper investigates the effect of radial and azimuthal mode spacings in a 25-channel MDM-WDM system in MMF using a spatial light modulator-cont...
متن کاملInce-Gaussian modes of the paraxial wave equation and stable resonators.
We present the Ince-Gaussian modes that constitute the third complete family of exact and orthogonal solutions of the paraxial wave equation in elliptic coordinates and that are transverse eigenmodes of stable resonators. The transverse shape of these modes is described by the Ince polynomials and is structurally stable under propagation. Ince-Gaussian modes constitute the exact and continuous ...
متن کاملOptimal beam forming for laser beam propagation through random media
Focusing optical beams on a target through random propagation media is very important in many applications such as free space optical communications and laser weapons. Random media effects such as beam spread and scintillation can degrade the optical system’s performance severely. Compensation schemes are needed in these applications to overcome these random media effects. In this research, we ...
