The metacanvas is a completely new generation of technology compared to all previous works. It is a tunable photonic devices based on vanadium dioxide that is lithography-free and fully reconfigurable. oth the patterns and the functionalities of the metacanvas can be arbitrarily reconfigured, which leads to many more degrees of freedom in metasurface design and functionalities. One piece of metacanvas is able to function as different optical components – hologram, phase-array, polarizer, modulator, etc. – at different times and on command, which has never been achieved in any of the previous VO2.
