Surface-emitting [SE] lasers, e.g. having both horizontal and vertical cavities

Introduced: January 2000

Full Title

Full titles differ between systems:

IPC:

Semiconductor lasers > Construction or shape of the optical resonator > Surface-emitting [SE] lasers, e.g. having both horizontal and vertical cavities

CPC:

Semiconductor lasers (superluminescent diodes H10H20/00) > Construction or shape of the optical resonator > Surface-emitting [SE] lasers, e.g. having both horizontal and vertical cavities

IPC and CPC are identically structured here. All 2 subcodes exist in both systems.

1 shared codes have differing titles between IPC and CPC.

IPC defines codes here since 2000.
