Integrated Photonic Devices and Materials GroupSolomon Assefa was a member of Prof. Kolodziejski's research group from 1999 to 2004 earning a Ph.D. in 2004 and a Masters in Engineering in 2001 from the Department of Electrical Engineering and Computer Science. He conducted research in use of photonic crystals, in particular the photonic crystals composed of dielectric rods in the GaAs/aluminum oxide material system resulting in a Ph.D. thesis titled "The Development of Novel Passive and Active Photonic-Crystal Devices" and a M.Eng. thesis titled "Design and Fabrication of Sharp Bend Photonic Crystal Slab Waveguides." He also investigated the initial fabrication of an electrically activated photonic crystal laser. He is currently employed at IBM T.J. Watson Research Center.
