Fabrication of diffractive-reflective optical interconnects for infrared operation based on total internal reflection.
Diffractive-reflective optical interconnects (DROIs) for optical chip-to-chip interconnection were introduced in a 1988 paper. In this paper we demonstrate the use of total internal reflection for guiding the light. inside the glass plate. The required holographic grating couplers were produced by expoiting the wavelength change from blue light recording to red light reconstruction. Several types of fan-out DROI have been made in dichromated gelatin.
