Modes are idempotent and entropic algebras. Although it had been established many years ago that groupoid modes embed as subreducts of semimodules over commutative semirings, the general embeddability question remained open until Stronkowski and Stanovský's recent constructions of isolated examples of modes without such an embedding. The current paper

A mode is an idempotent and entropic algebra, i.e., every singleton is a subalgebra and each operation is a homomorphism. A mode is \(n\)-step left reductive if it has a binary term and satisfies the identity: \[ x_1\cdot (x_2\cdot \dots(x_n\cdot y)\dots)=x_1\cdot(x_2\cdot\dots(x_n\cdot z)\dots).

A new family of paraxial laser beams that form an orthogonal basis is discussed. When propagated in uniform space, these beams preserve their structure to scale. The intensity distribution profile for such beams is similar to that for the Bessel modes, representing a set of alternating bright and dark concentric rings.

Tapered Mode Multiplexers for Single Mode to Multi Mode Fibre Mode Transitions
Optical Fiber Communication Conference, 2015Three-mode multiplexers were made by post-processing existing SMF-28 fibres. The input was three identical SMFs which were fused together and adiabatically tapered to form a multimode output core. The light was converted to the LP 01 and two LP 11 with low loss (0.6–0.7 dB). The mode multiplexers were broadband.

This chapter examines three recent works of fiction by Francophone writers that represent with pressing detail the dilemmas faced by migrants who risk everything in an attempt to reach northern shores. The reasons behind these departures are multiple, but most migrants are motivated by more than simplified facts.

Mode measurement of few-mode fibers by mode-frequency mapping
Optics Letters, 2018Since few-mode fibers (FMFs) have great potential as the new transmission media for optical communications, the ability to distinguish different fiber modes is essential. Most of the traditional schemes do not yield phase information, or are limited by beam size and mechanical requirements.
