(DE) LASERDIODE UND VERFAHREN ZUM HERSTELLEN EINER LASERDIODE
Abstract:
(EN) The invention relates to a laser diode (1) comprising - a surface-emitting semiconductor laser (10) which is designed to emit electromagnetic radiation (E), and - an optical element (20) which is arranged downstream of the semiconductor laser (10) in an emission direction (L), wherein - the optical element (20) has a diffractive structure (200) or a meta-optical structure (200) or a lens structure (200), and - the optical element (20) and the semiconductor laser (10) are integrally connected to one another.
(FR) L’invention concerne une diode laser (1) comprenant : - un laser à semi-conducteur à émission de surface (10) adapté pour émettre un rayonnement électromagnétique (E), et - un élément optique (20) disposé en aval du laser à semi-conducteur (10) dans une direction de rayonnement (L), - l’élément optique (20) comportant une structure de diffraction (200) ou une structure méta-optique (200) ou une structure de lentille (200), et - l’élément optique (20) et le laser à semi-conducteur (10) étant reliés par liaison de matière.
(DE) Laserdiode (1) umfassend - einen oberflächenemittierenden Halbleiterlaser (10), welcher dazu eingerichtet ist elektromagnetische Strahlung (E) zu emittieren, und - ein optisches Element (20), welches dem Halbleiterlaser (10) in einer Abstrahlrichtung (L) nachgeordnet ist, wobei - das optische Element (20) eine diffraktive Struktur (200) oder eine Meta-Optik-Struktur (200) oder eine Linsenstruktur (200) umfasst, und - das optische Element (20) und der Halbleiterlaser (10) stoffschlüssig miteinander verbunden sind.
