G02F 1/03 based on ceramics or electro-optical crystals, e.g. exhibiting Pockels effect or Kerr effect (G02F1/061 takes precedence)
Introduced: July 1974
Title
Titles differ between systems:
IPC: based on ceramics or electro-optical crystals, e.g. exhibiting Pockels or Kerr effect
CPC: based on ceramics or electro-optical crystals, e.g. exhibiting Pockels effect or Kerr effect (G02F1/061 takes precedence)
Full Title
Full titles differ between systems:
Devices or arrangements for the control of the intensity, colour, phase, polarisation or direction of light arriving from an independent light source, e.g. switching, gating or modulating; Non-linear optics > for the control of the intensity, phase, polarisation or colour > based on ceramics or electro-optical crystals, e.g. exhibiting Pockels or Kerr effect
Devices or arrangements for the control of the intensity, colour, phase, polarisation or direction of light arriving from an independent light source, e.g. switching, gating or modulating; Non-linear optics > for the control of the intensity, phase, polarisation or colour (G02F1/29, G02F1/35 take precedence) > based on ceramics or electro-optical crystals, e.g. exhibiting Pockels effect or Kerr effect (G02F1/061 takes precedence)
CPC subdivides this area 3x more granularly than IPC with 5 additional codes.
5 codes are CPC-only extensions.
2 shared codes have differing titles between IPC and CPC.
IPC defines codes here since 1974.
