<i>λ</i> ∼ 4.7 μm Quantum Cascade Distributed-Feedback Lasers for Free-Space Communications

Quantum cascade lasers (QCLs) have emerged as promising candidate sources for free-space communications. High optical power densities, short photon lifetimes, and low internal capacitance are important factors influencing the transmission bandwidth. We report the design and fabrication of 4.7 <in...
