%X The explicit expressions of minimum classical wavepackets are generally derived by using the operator technique of quantum mechanics.The problem of optical wavepackets travelling in vacuum is taken as an example to investigate the meaning of complex functions and negative frequency in classical physics.The central frequency of complex Gaussian wavepackets can be freely adjusted through the displacement parameter and squeeze factor. Some other characters of the minimum optical wavepackets are also studied.
