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

URL: www.iso.org/iso/foreword.html.

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.

Any feedback or questions on this document should be directed to the user’s national standards body. A

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.

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.

define a unified vocabulary at a time when the first products are coming onto the market. 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, International electrotechnical

vocabulary. Wherever this can lead to misunderstanding, integrated optics or integrated optical
