ISO/TC 172/SC 9/WG 7 - Electro-optical systems other than lasers

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.

This document defines basic terms for integrated optical devices, their related optical chips and optical elements which find applications, for example, in the fields of optical communications and sensors. — The coordinate system used in Clause 3 is described in Annex A. — The symbols and units defined in detail in Clause 3 are listed in Annex B.

This document defines terms used in the classification of integrated optical elements, integrated optical components and integrated optical devices, which find applications, for example, in the fields of optical communications and sensors.

This document defines the basic terms for diffractive optical elements for free space propagation. The purpose of this document is to provide an agreed-upon common terminology that reduces ambiguity and misunderstanding and thereby aid in the development of the field of diffractive optics.

This document defines terms for microlens arrays. It applies to arrays of very small lenses formed inside or on one or more surfaces of a common substrate. This document also applies to systems of microlens arrays.

ISO 17901-1:2015 specifies the terms related to optical characteristics of holograms, the method to measure their diffraction efficiency, and the angular and wavelength selectivity measurement methods. These measurement methods are applicable to any type of hologram if the hologram yields a simple diffraction pattern, which means the reconstructed wave can be clearly separated from other diffracted and non-diffracted waves. In other words, holograms that yield complex diffraction patterns are excluded. There are no restrictions on the materials used to form the holograms.

ISO 17901-2:2015 specifies the terms and measurement method concerning exposure characteristics (exposure characteristic curve, exposure at half-maximum, R-value, amplitude of refractive index modulation) for the hologram recorded by double-beam interference. The materials of hologram to be measured are not restricted to any particular ones. ISO 17901-2:2015 does not intend to restrict manufacturing process.

ISO/TR 14880-5:2010 gives guidelines for the testing of microlenses. It applies to microlenses in arrays where very small lenses are formed inside or on one or more surfaces of a common substrate. ISO/TR 14880-5:2010 addresses the measurement of optical and geometrical properties of single microlenses as well as microlens arrays. When testing a microlens or microlens array, the test method is selected according to the parameters to be measured, the size and structure of the microlens and its application. ISO/TR 14880-5:2010 guides the user to select the appropriate measurement method from the available ISO standards.

ISO 14880-3:2006 specifies methods for testing optical properties, other than wavefront aberrations, of microlenses in microlens arrays. It is applicable to microlens arrays with very small lenses formed on one or more surfaces of a common substrate and to graded index microlenses.

ISO 14880-4:2006 specifies methods for testing geometrical properties of microlenses in microlens arrays. It is applicable to microlens arrays with very small lenses formed on one or more surfaces of a common substrate and to graded index microlenses.

ISO 14880-2:2006 specifies methods for testing wavefront aberrations for microlenses within microlens arrays. It is applicable to microlens arrays with very small lenses formed inside or on one or more surfaces of a common substrate.

ISO 14880-1:2016 defines terms for microlens arrays. It applies to microlens arrays which consist of arrays of very small lenses formed inside or on one or more surfaces of a common substrate and systems. The aim of ISO 14880-1:2016 is to improve the compatibility and interchangeability of lens arrays from different suppliers and to enhance the development of technology using microlens arrays.

ISO 15902:2004 defines the basic terms for diffractive optical elements for free space propagation. The purpose of these definitions is to provide an agreed-upon common terminology that will reduce ambiguity and misunderstanding and thereby aid in the development of the field of diffractive optics.
