Paper Abstract

A synchronized broad-area laser array (SBLA) can produce a highly coherent light source whose output intensity is proportional to the square of the number of lasers in the array. High contrast optical intensity modulation can be achieved by utilizing the nonlinear response of the total output intensity to the injected light, resulting in fast optical switching. SBLA can be applied to phased array antenna and beam steering. Semiconductor laser array capability provides a unique opportunity not only for free-space adaptive optical communication but also for free-space quantum adaptive optical communications through the atmosphere. In this paper, we propose a paradigm that illustrates how quantum communication (which provides quantum ultra-security) can take advantage of ultrashort pules, high repetition rate, high power density (due to coherent beam coupling), and spatial beam control.
