(54) Lens with gradient <strong>in</strong>dex of refraction<br />
(57) The <strong>in</strong>vention relates to the field of optoelectronics<br />
and may be used <strong>in</strong> the fiber-optic data<br />
transmission systems and <strong>in</strong> the data record-<br />
<strong>in</strong>g-read<strong>in</strong>g systems by means of the optical<br />
carrier.<br />
Summary of the <strong>in</strong>vention consists <strong>in</strong> that the<br />
lens with gradient <strong>in</strong>dex of refraction conta<strong>in</strong>s<br />
a light-<strong>in</strong>sulat<strong>in</strong>g shell with core, placed <strong>in</strong>side<br />
the <strong>in</strong>ductance coil. With that the shell is made<br />
<strong>in</strong> the form of a plastic tube and the core is<br />
made <strong>in</strong> the form of a colloidal suspension of<br />
Y 3 Fe 5 O 12 powder <strong>in</strong> polyethylsiloxane oil.<br />

(54) Fibră optică cu focalizare automată<br />
(57) Invenţia se referă la domeniul optoelectronicii<br />
şi poate fi utilizată în sistemele de transmitere<br />
a <strong>in</strong>formaţiei pr<strong>in</strong> fibre optice.<br />
Esenţa <strong>in</strong>venţiei constă în aceea că fibra optică<br />
cu focalizare automată conţ<strong>in</strong>e un înveliş cu miez<br />
amplasat între doi electrozi de dirijare. Totodată<br />
învelişul este executat ca un tub de masă plastică,<br />
iar miezul - ca o suspensie coloidală de<br />
prafuri PbTiO 3 şi SrTiO 3 în ulei de polietilsiloxan.<br />

(54) Self-focus<strong>in</strong>g optical fiber<br />
(57) The <strong>in</strong>vention relates to the field of optoelectronics<br />
and may be used <strong>in</strong> the fiber-optic data<br />
transmission systems.<br />
Summary of the <strong>in</strong>vention consists <strong>in</strong> that the<br />
self-focus<strong>in</strong>g optical fiber conta<strong>in</strong>s a shell with<br />
a core, placed between two control electrodes.<br />
PATENTS<br />
With that the shell is made <strong>in</strong> the form of a plastic<br />
tube, and the core – <strong>in</strong> the form of a colloidal<br />
suspension of PbTiO 3 and SrTiO 3 powders <strong>in</strong><br />
the polyethylsiloxane oil.<br />
