Overview

IEC 60747-5-4:2022/AMD1:2024 is Amendment 1 to the international standard IEC 60747-5-4, focusing on optoelectronic semiconductor lasers. Published by the International Electrotechnical Commission (IEC), this amendment refines definitions and measurement methods relevant to the performance and characterization of semiconductor lasers, a critical component in modern optoelectronic devices.

This amendment ensures the standard remains aligned with advances in technology, reflecting the consensus of an international network of experts. Adhering to IEC 60747-5-4 and its amendments supports compatibility, reliability, and quality in optoelectronics and laser-based applications worldwide.

Key Topics

• Refined Terminology and Definitions: Updates to technical definitions, particularly for relative intensity noise (RIN), to harmonize with current industry and research practices.
• Standardized Performance Characteristics: Modifications in measurement conditions and output parameters, with clarified requirements for electrical and optical characteristics.
• Measurement Methods: Detailed approaches for specifying parameters such as threshold current, output power, peak wavelength, spectral bandwidth, divergence angles, rise/fall times, and noise characteristics.
• Documentation Guidance: Emphasis on consistent data sheet presentation and parameter reporting for manufacturers and end-users.
• Application of Normative References: Reinforcement of reference to related IEC and ISO standards applicable to optoelectronic semiconductor devices.

Applications

Conformance to IEC 60747-5-4:2022/AMD1:2024 is vital for:

• Manufacturers of Semiconductor Lasers: Ensures product benchmarks meet international expectations for reliability, safety, and performance.
• Quality Assurance and Testing Laboratories: Enables objective comparison and evaluation of optoelectronic devices by applying standardized measurement protocols.
• System Integrators and Design Engineers: Facilitates selection, integration, and troubleshooting of semiconductor lasers in telecommunications, sensing, medical equipment, and industrial automation.
• Technical Documentation and Procurement: Provides a reliable framework for technical specifications, purchase contracts, and compliance verification.
• Regulatory and Certification Bodies: Supports certification and conformity assessment programs by specifying measurable, internationally recognized requirements.

End-products that benefit from the adoption of this standard include:

• Fiber-optic transmitters and receivers
• Barcode scanners and optical sensors
• Medical diagnostic devices
• Laser-based measurement instruments
• Consumer electronics with integrated laser technology

Related Standards

IEC 60747-5-4:2022/AMD1:2024 is part of the broader IEC 60747 series, addressing semiconductor devices. For comprehensive implementation and compliance, consideration of related standards is essential:

• IEC 60747 (Main Series): The foundational series for semiconductor device standards.
• IEC 60747-5-1: General standards for optoelectronic devices.
• ISO 11145: Standard for laser and laser-related equipment - laser divergence angle measurement.
• ISO 11146-1: Specifies methods for measuring laser beam widths, divergence angles, and astigmatic differences.

For the latest information and any future revisions or corrigenda, users should consult the IEC Webstore and related ISO resources.

Practical Value

Adhering to IEC 60747-5-4:2022/AMD1:2024 enhances product interoperability in the global marketplace, streamlines the development of high-quality optoelectronic systems, and supports trust across supply chains. By implementing these internationally agreed-upon definitions and methods, organizations minimize ambiguity, ensure safety, and improve innovation in semiconductor laser technology.

AMENDMENT 1
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position con
