H01S 5/187

using Bragg reflection

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

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) > using Bragg reflection

No child classifications to compare. This is a leaf node in both IPC and CPC.
