TS EN ISO 11807-1

TS EN ISO 11807-1 is a vocabulary standard for integrated optics, defining the basic terms and symbols used in this field. It provides a common technical language for optical waveguides, related optical chips, and optical elements, which is especially useful when discussing components employed in optical communications and sensor applications.

How the terminology fits integrated-optics design

In integrated optics, light is guided and manipulated within structures fabricated on a substrate rather than propagated only through free space. That makes concepts such as waveguide geometry, guided modes, coupling, propagation direction, and refractive-index contrast central to design and measurement. By standardizing the basic vocabulary, this document helps engineers, manufacturers, and users describe the same physical structures and functions with less ambiguity.

What this part explicitly brings together

The scope states that the document defines basic terms for integrated optical devices, their related optical chips, and optical elements. It also notes that the coordinate system used in Clause 3 is described in Annex A, while the symbols and units detailed in Clause 3 are listed in Annex B. In practice, that means the standard is not only about definitions but also about a consistent notation framework that supports drawings, calculations, and technical documentation.

• Basic vocabulary for integrated optical devices
• Terms for related optical chips and optical elements
• A coordinate-system convention linked to Annex A
• Symbols and units linked to Annex B
• Technical context relevant to communications and sensors
