Paper Abstract

Polarization dependence of photopolymer-based volume holograms for substrate-guided-wave optical interconnects with surface normal configuration is investigated. Energy optimization and the tradeoff between energy equalization and polarization insensitivity of one-to- many cascaded interconnects are discussed. DuPont photopolymer film HRF 600X001-20 was employed in our experiment. A volume hologram with diffraction efficiency of 91.5%± 1.5% is achieved for different linearly polarized optical waves. A 1-to-9 fanout device with ± 5% energy fluctuation for a randomly polarized input optical wave at 632.8 nm has been fabricated for evaluating the trade-off under p and s waves. As the Mylar substrate of the photopolymer films has strong effects in changing incident linearly polarized light into elliptically polarized light, the energy uniformity of a practical device can be improved significantly. The developed theory is applicable to any volume hologram.
