The work highlighted on the cover of Applied Optics is the result of the collaboration of Japanese scientists from Kyosemi Corporation and Sphelar Power Corporation, and Pakistani and Turkish scientists working at Koç University. Visible on the cover is ethanol (top left), liquid crystal (bottom left), laser dye in ethanol (top right), and laser dye (bottom right) in liquid crystal solutions in a transparent plastic cuvette under green laser excitation, enhancing the omnidirectional response of the Sphelar One silicon spherical photocell.
