1.55 μm VCSEL based on InAs quantum-dashes with an emission covering 105 nm wavelength range
Résumé
We present an InP-VCSEL based on optimized InAs quantum-dashes (QDHs) nanostructures operating at telecommunication wavelength. Contrary to conventional quantum-wells (QWs) based VCSELs, InAs QDHs can be used as gain media in InP-VCSEL to achieve a stable and polarized laser emission. Here, we demonstrate an optically-pumped QDH based VCSEL, with a constant and control linear state of polarization, and showing a CW laser emission from 1647 down to 1542 nm, covering thus a spectral window as large as 105 nm.
