Описание (английский):

This document defines the relevant properties for coupling lightwaves into and out of integrated optical chips (IOC) and chips with photonic integrated circuits (PIC). This document mainly focuses on butt coupling via the waveguide endfaces. The definitions provide the basis for specifying the elements to be coupled (e. g. fibres, integrated optical chips) related to coupling properties.

Overview

EN ISO 14881:2021 - Integrated optics - Interfaces - Parameters relevant to coupling properties - is a CEN-adopted international standard that defines the vocabulary and key parameters for coupling lightwaves into and out of integrated optical chips (IOC) and photonic integrated circuits (PIC). The standard concentrates on butt coupling via waveguide endfaces, providing a unified set of definitions that form the basis for specifying elements to be coupled (e.g., optical fibres, fibre arrays, chips) with respect to coupling properties.

Key topics and technical requirements

The document standardizes terms and parameters relevant to optical coupling. Principal topics include:

Coupling geometry

Chip geometry and waveguide geometry (endface locations, chip surfaces, facets)
Beam axis and spot size descriptions for guided lightwaves

Coupling performance metrics

Coupling efficiency (η) - ratio of coupled power to emitted power
Coupling loss (αc) - logarithmic loss expressed in dB (caused by misalignment, mode mismatch, reflections)

Interface and endface properties

Endface quality, anti-reflective coatings, Fresnel loss
Index matching techniques (e.g., λ/4 layer) to reduce reflections

Fibre and array considerations

Fibre tolerances, pitch (centre-to-centre spacing), fibre array coupling and fibre array coupling deviation
Array block and fixed alignment structures for precise mechanical alignment

Normative references and harmonization

The standard references ISO 4288, ISO 11807-1/-2, and IEC 60793-1-20 and aligns terminology with related IEC definitions.

EN ISO 14881:2021 focuses on definitions and parameterization rather than prescribing measurement procedures; it provides the vocabulary and parameters used when specifying and testing coupling interfaces.

Practical applications

This standard is practical for anyone specifying, designing or testing optical interfaces where efficient fibre-to-chip or chip-to-chip coupling is required. Typical uses include:

Specifying fibre-to-PIC interfaces and acceptance criteria for coupling loss and efficiency

Design and tolerancing of waveguide endfaces, chip facets and anti-reflective coatings

Engineering of fibre arrays, V-groove array blocks and fixed alignment structures

Test-laboratory reporting and supplier–customer contracts that reference unified coupling parameters
