Abstract: A method of forming an optical interconnect between first and second photonic chips located on an optical printed circuit board includes applying a flexible, freestanding film onto the first and second chips so that the film extends over a gap and/or step between the chips. The film includes a photosensitive layer having a refractive index that decreases by exposure to radiation and a backing layer. The film is exposed to a flood exposure having a radiation dosage penetrating the backing layer and only a surface sublayer of the photosensitive layer. After curing the film, the backing layer is removed so that the photosensitive layer remains on the first and second chips. The photosensitive layer is selectively exposed to a second radiation dosage to define waveguide core(s) in unexposed regions of the photosensitive layer below the surface sublayer. The photosensitive layer is heated to cure the selectively exposed portions.

Abstract: A photovoltaic (“PV”) module may comprise an array of freeform micro-optics and an array of PV cells. The PV module may be a flat panel with a nominal thickness smaller than the length and width of the flat panel. An array of lenses may be embedded in an array substrate. The lenses may be coupled to light pipes. The lenses may concentrate light through the light pipes to multi junction cells. Diffuse light may be transferred through the array substrate to a silicon cell. The lenses and light pipes may be manufactured using a molding and drawing process.
