Part 19: Photonic chip scale package

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) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 62148-19 has been prepared by subcommittee 86C: Fibre optic
systems and active devices, of IEC technical committee 86: Fibre optics.
The text of this International Standard is based on the following documents:

INTRODUCTION
A photonic chip scale package is used to convert electrical signals into optical signals and vice-
versa. This document covers the physical interface for photonic chip scale packages. These

4 Classification
The photonic chip scale package specified in this document is classified as type 5 according to
the definitions of IEC 62148-1.
5 Specification of photonic chip scale package
5.1 General
Clause 5 specifies the physical requirements of a photonic chip scale package that will enable
mechanical interchangeability of modules complying with this document, both for the PCB and
for any panel mounting requirement.
5.2 General block diagram (silicon photonics)
The block diagram for the photonic chip scale package is shown in Figure 1, which contains N
channels of electrical inputs, M channels of electrical outputs, Q channels of optical outputs,
and R channels of optical inputs.
The functions of electrical to optical (E/O) conversion or/and optical to electrical (O/E)
conversion are provided by the package according to applications.
Channel numbers of electrical inputs N and optical outputs Q in E/O and optical inputs R and
electrical outputs M in O/E are determined according to a multiplexing scheme such as
wavelength multiplexing and serializer/deserializer.
Specific configurations for the photonic chip scale package are shown in Annex A.

5.3 Electrical interface
5.3.1 General
The electrical interface in this document defines only the basic functionality of each terminal.
5.3.2 Numbering of electrical terminals
Electrical terminal numbering assignments are shown in Figure 2. The location of reference
electrical terminal A1 is assigned at bottom left corner, and the direction of the package is
decided by the position of the optical interface shifted to the left of centre, as shown in Figure 2.

Figure 2 – Electrical terminal numbering assignment (top view)
5.4 Optical interface
5.4.1 General
The optical interface in this document defines only the basic functionality of each optical
terminal. The channel spacing of optical interface has two options of 0,25 mm and 0,125 mm.
5.4.2 Free space optical beam condition
The optical output beam from a surface of the photonic chip scale package is coupled to an
optical fibre or optical waveguide with free space optics, such as optical lenses or butt coupling,
to have a specific coupling efficiency designed by each vendor.
Dimension of optical terminals and beam profiles are characterized in accordance with the
vendor’s specification.
5.5 Outline and footprint
5.5.1 General
The footprint of the photonic chip scale package is determined by the number of channels of
the optical transmitter and/or receiver and the dimensions and pitch of the electrical terminals.
The electrical pad pitch and dimensions of the chip follow the general guidance for a chip scale
package (IEC 62148-21).
