actually i am working on optical RAM, i worked at half addder circuit also. this circuit is suggested by my senior but i was unable to find output every time desired result , only noise occure , i am using optisysatem 7, in my lab only optisystem 7 available, so for my thesis, i have no option only work with optisystem 7. can you attach basic circuit of optical adder which i can implement using optisystem 7.
Thanks
