His research, largely funded by multiple branches of the U.S. DoW and national laboratories, has had direct and tangible impact on various defense capabilities, with many developed devices and platforms successfully commercialized. His contributions include the first InP-based QCLs grown on lattice-mismatched substrates, independent demonstration of the first QCLs-on-Si, world-record-performance QCL-on-Si devices integrated on 8-inch silicon wafers, dual-band high-power CW QCLs, record-setting multiwatt CW QCLs in the MWIR and LWIR, high-brightness broad-area QCLs, QCL tree-arrays for scalable high-power systems, and ultrafast broadly tunable QCLs for standoff sensing and diagnostics. He has authored over 40 peer-reviewed publications, four book chapters, and holds 16 patents.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"excerpt":{"rendered":"Dr. Arkadiy Lyakh has more than 25 years of experience in semiconductor laser research and development, with a primary focus on low-dimensional semiconductor devices, particularly quantum cascade lasers (QCLs).
