H01S 5/185

having only horizontal cavities, e.g. horizontal cavity surface-emitting lasers [HCSEL] (comprising a photonic bandgap structure H01S5/11)

Introduced: January 2021

Title

Titles differ between systems:

IPC: having only horizontal cavities, e.g. horizontal cavity surface-emitting lasers [HCSEL]

CPC: having only horizontal cavities, e.g. horizontal cavity surface-emitting lasers [HCSEL] (comprising a photonic bandgap structure H01S5/11)

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 > having only horizontal cavities, e.g. horizontal cavity surface-emitting lasers [HCSEL]

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 > having only horizontal cavities, e.g. horizontal cavity surface-emitting lasers [HCSEL] (comprising a photonic bandgap structure H01S5/11)

IPC and CPC are identically structured here. All 1 subcodes exist in both systems.

IPC defines codes here since 2000.
