Wideband optical signal processing for adaptive antennas calls for a high-performance spatial light amplifier (SLA). The latter can be implemented as an upgrade of micro-channel SLA by replacing bulk crystal with a single-crystal fiber array (SCFA). This paper is focused on SCFA fabrication. The design process from specifying SCFA parameters to selecting fabrication technique (dice-and-fill or laser-heated pedestal growth) is reviewed. The results achieved with the dice-and- fill method are presented.
