Light emitting device with extended mode-hop-free spectral tuning ranges and method of manufacture

摘要

Laser with extended mode-hop free spectral tuning ranges and methods for manufacturing such lasers are disclosed. In an embodiment the method includes providing a light emitting device, the light emitting device comprising a gain region and a first wavelength selection region and mounting the light emitting device on a thermally conductive carrier such that the gain region is mounted on a first carrier surface and the first wavelength selection region is arranged over and spaced apart from a second carrier surface.
