BLOCK PARTY: Three blocks of gradient index polymer demonstrate their differing indices of refraction in the laboratory of Duncan Moore 鈥�74 (PhD), the Rudolf and Hilda Kingslake Professor of Optical Engineering at the Institute of Optics. As a three-color 鈥渨hite light鈥� laser passes through the blocks, the light bends toward the side of each block with a larger index of refraction. Since each of the three colors bends at a different rate, the beam spreads out into its separate color components. Photograph by Adam Fenster锘�
