Broadband Distributed Feedback Quantum Cascade Laser Array Using A Heterogeneous Cascade

Not Accessible

Your library or personal account may give you access

Abstract

We demonstrated an array of distributed feedback quantum cascade lasers covering a spectral range of 220cm−1. The variability in threshold current and slope efficiency is explained in terms of the position of the laser end facets.
