Not Accessible

Your library or personal account may give you access

Abstract

We demonstrated a compact VCSEL amplifier with a folded waveguide layout. Light propagation and amplification are realized in all 8 arms of the waveguide. Output power of 330mW and narrow divergence of 0.1° were obtained.
