Integrated optics - Interfaces - Parameters relevant to coupling properties (ISO 14881:2021)

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.

Integrierte Optik - Schnittstellen - Kopplungsrelevante Parameter (ISO 14881:2021)

Dieses Dokument definiert die Eigenschaften, die für die Kopplung von optischen Wellen in und aus integriert-optischen Chips (IOC) und chip-integrierten photonischen Schaltungen (PIC, en: chips with photonic integrated circuits) relevant sind. Dieses Dokument ist auf Stoßkopplung über die Wellenleiter-Endflächen beschränkt. Die Definitionen ermöglichen eine Grundlage für die Spezifizierung der zu koppelnden Elemente (z. B. Fasern, integriert-optische Chips) in Bezug auf die Koppeleigenschaften.

Optique intégrée - Interfaces - Paramètres caractérisant les propriétés de couplage (ISO 14881:2021)

Le présent document définit les propriétés qui caractérisent le couplage des ondes lumineuses à l’entrée et la sortie de circuits optiques intégrés (IOC) et de circuits avec circuits photoniques intégrés (PIC). Le présent document se concentre sur le couplage en about par l’intermédiaire des faces des guides d’ondes. Les définitions fournissent la base de spécification des éléments à coupler (par exemple, fibres, circuits optiques intégrés) par rapport aux caractéristiques de couplage.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation on the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see the following

This document was prepared by Technical Committee ISO/TC 172 Optics and photonics, Subcommittee SC
9, Laser and electro optical systems. In collaboration with the European Committee for Standardization
(CEN) Technical Committee CEN/TC 123, Lasers and photonics , in accordance with the agreement on
technical cooperation between ISO and CEN (Vienna Agreement).
This second edition cancels and replaces the first edition (ISO 14881:2001), which has been technically
revised. The main changes compared to the previous edition are as follows:
— Terminologies that have not been frequently used over the last 5 to 10 years are revised to those
matching to current trends.
— In the revision process, terminologies and definitions are compared to similar terminology
definitions in IEC and harmonized.

Introduction
The aim of this document is to clarify the terms of the field of “integrated optics” and to define a unified
vocabulary. It is expected that this document will be revised periodically to adopt the requirements of
customers and suppliers of integrated optical products. At a later stage, it is planned to add definitions
from other International Standards which deal with integrated optics.
Some of the definitions are closely related to definitions given in IEC 60050-731. Wherever this can lead
to misunderstanding, integrated optics or integrated optical waveguide should be used together with
the defined term.
