| Term (EN) | leaky ray, tunnelling ray |
|---|
| Definition (EN) | In an optical fibre, a light ray for which geometric optics would predict total reflection at the core boundary, but which suffers a loss unexplained by this theory, by virtue of the curved core boundary.
Note. — Leaky rays correspond to leaky modes. |

| Definition (SR) | U optičkom vlaknu, svjetlosni zrak za koji geometrijska optika predviđa totalnu refleksiju na granici jezgre, ali koji pretrpi gubitke neobjašnjive po ovoj teoriji, zahvaljujući zaobljenim granicama jezgre.
Napomena — Propusne zrake odgovaraju propusnom modu. |
