    Awarded multilayer coatings design

    team — Dr. Michael Trubetskov won four First Prizes in Design Contest Awards (Optical Interference Coatings Topical Meeting 2016) of the Optical Society of America (OSA). The first design problem of this year involved a dispersive mirror with maximum negative GDD (sub-problem A1) and with specified GDD level (sub-problem A2). In both cases the allowed GDD oscillation level was limited to 10%. The second problem was related to the design of a reflector with complicated spectral reflectance (sub-problem B1). In sub-problem B2 it was necessary to take into account complicated multilayer deposition conditions and to optimize overall performance. The contest takes place every three years, in order to better understand the possibilities and limitations of the current state-of-the-art theory/software for optical interference coatings. In this contest 18 participants from Germany, USA, France, Japan, China took place. The results of the Design Contest will be published in the featured issue of Applied Optics devoted to OIC 2016.
