Integrated optical circuits characterised by the manufacturing method

Introduced: January 1995

Full Title

Full titles differ between systems:

IPC:

Light guides; Structural details of arrangements comprising light guides and other optical elements, e.g. couplings > of the optical waveguide type > of the integrated circuit kind > Integrated optical circuits characterised by the manufacturing method

CPC:

Light guides; Structural details of arrangements comprising light guides and other optical elements, e.g. couplings > of the optical waveguide type (G02B6/02, G02B6/24 take precedence; devices or arrangements for the control of light by electric, magnetic, electro-magnetic or acoustic means G02F1/00; transferring the modulation of modulated light G02F2/00; optical logic elements G02F3/00; optical analogue/digital converters G02F7/00) > of the integrated circuit kind (electric integrated circuits H10B, H10D84/00 - H10D89/00, H10F19/00, H10F39/00, H10H29/00, H10K19/00, H10K39/00, H10K59/00, H10N19/00, H10N39/00, H10N59/00, H10N69/00, H10N79/00, H10N89/00) > Integrated optical circuits characterised by the manufacturing method

Of 5 combined children, 4 exist in both systems.

1 codes are CPC-only extensions.

IPC defines codes here since 1995.
