| Research Abstract |
We investigated the propagation of transverse two-dimensional images encoded on optical pulses through image resonators. The Fourier method shows that as long as the spatial and temporal Fourier components of the image were within the bandwidth of the amplitude and phase transfer functions, image can propagate through the resonator successfully and the relevant steep dispersion of the cavity can yield delayed or advanced images, that is, "slow image" and "fast image". The slow and fast images were experimentally demonstrated in the single stage image resonator on the over- or under-coupling condition, as well as in an induced transparency frequency window of a coupled-image-resonator.
