Zusammenfassung:	Photonic integrated circuits have been designed, simulated, and tested on TriPleX™ platform technology for implementing optical Haar Transform (HT) in the visible spectrum. Optical circuits contain the new building block (BB), designed using the multimode interference (MMI) structure, performing optical HT on a pair of the optical signals. The Outputs of the BB demonstrate the sum and subtraction of the input signals according to the HT operation. 1st-order and 2nd-order optical HT achieved for the green light input signals. Simulation and experimental results have successfully validated the designed photonic circuits’ capability in implementing optical HT.
