In this paper we demonstrate the capability of OptoVLSI processors to generate arbitrary optical power distribution for adaptive optical beam splitting and dynamic optical spot generation. By using the multicasting capability of Opto-VLSI processors, an input optical signal can be dynamically split into N spots array, and the output power of each spot can be independently configured. Experimental results of multiple beam splitting show that dynamic optical multicasting can be achieved with more than 20dB dynamic range. Special patterns are also generated by optimising the phase hologram of the Opto-VLSI processor to place the output beam spots at appropriate positions.
