In theory yes. For example, certain optical elements perform Fourier transforms. However optical computing as we know it today is really a type of analog computer. Today’s optical devices are relatively large compared to transistors so difficult to make an optical computer scale very well. Also given that each optical computing stage involves optical power loss, there’s a limit to how many stages one can cascade before having to regenerate via an OEO conversion.
