Cross-link optimized cascaded volume hologram array with energy-equalized one-to-many surface-normal fan-outs
Abstract:
Achieving a uniform fan-out energy distribution is critical to the successful applications of substrate guided-wave optical interconnects. Using Dupont photopolymer film HRF-600X00120, we investigated the optimum recording beam intensity for obtaining a large dynamic region of diffraction efficiency relative to exposure dosage. Based on the experimental diffraction efficiency curve, 1-to-5 and 1-to-9 surface-normal fan-out devices were fabricated that operated at a wavelength of 850nm, and output nonuniformities of +/-4 % and +/-10 % were obtained for the two devices.
