Abstract
Various components needed for optical backplane applications have been demonstrated from gelatin-based polymer integrated op[tic material. An array of waveguides have been realized with packaging density as high as 1250 channels per cm and loss of 0.1 dB per cm. A 1-to-8 Y-junction splitter and a 32 x 32 star coupler have been fabricated using photolithographic techniques. The unification of the star coupler and a modulator array is for backplane optical interconnects is under investigation.
