Abstract:

THIS PHASE I PROPOSAL IS CONCERNED WITH THE DEVELOPMENT OF A VERSATILE WRITE/READ INTERCONNECTION DEVICE FOR BIT AND HOLOGRAPHIC ENCODED MEMORIES. THE PROPOSED DEVICE CONSISTS OF AN ARRAY OF MIRRORS WHOSE FOCAL LENGTHS CAN BE INDIVIDUALLY CONTROLLED BY A VLSI CHIP CONSISTING OF A 2-D ARRAY OF IDENTICAL DRIVE CIRCUITS. THE VLSI CHIP IS BUMP-BONDED TO THE ONE SIDE OF AN OPTRON PROPRIETARY COMPONENT CALLED A CHARGE-TRANSFER PLATE (CTP) AND A MEMBRANE MIRROR IS BONDED TO THE OTHER SIDE OF THE CTP OVER AN ARRAY OF PIXEL WELLS. THE ROLE OF THE CTP IS TO TRANSFER THE VOLTAGE FROM THE VLSI CHIP TO THE MEMBRANE WELLS. IN THE PHASE I PROGRAM WE PLANE TO FABRICATE A PROTOTYPE DEVICE HAVING 25 um DIAMETER MIRROR ON 30 um CENTERS AND ATTEMPT TO DEMONSTRATE ELECTRICALLY VARYING THE FOCAL LENGTHS OF THE MIRRORS FROM INFINITY TO ABOVE 1 cm. WE WILL FURTHER CHARACTERIZE THE DEVICE BY MEASURING SPOT SIZES AS A FUNCTION OF THE FOCAL LENGTH OF THE MIRRORS, FOCAL LENGTH AS A FUNCTION OF ADDRESSING VOLTAGE, AND THE OPTICAL EFFICIENCY OF THE ARRAY. THE MEASUREMENTS WILL BE CORRELATED WITH CALCULATED VALUES.
