Title

High-brightness quantum well and quantum dot tapered lasers

Other Title
Hochbrilliante Quantenfilm- und Quantenpunktlaser
Abstract
Several types of high-brightness near-infrared tapered quantum well and quantum dots tapered lasers are reviewed and compared. Recent developments include record-high brightness quantum well tapered lasers at 810 nm and 975 nm (up to 8.3 W CW, diffraction limited), high wall-plug efficiency gain-guided and index-guided tapered lasers (up to 57%), narrow slow axis far-field (2.5° FWHM) index-guided tapered lasers at 975 nm, wavelength-stable (down to 0.09 nm/K), high-brightness quantum dots tapered lasers at 920 and 975 nm, and quantum dots tapered lasers bars (up to 14 W CW) at 920 nm, with narrow far-field in the slow axis (3° FWHM).
