The present invention provides an improved fiber optic cross connect (OXC) package which reduces the size of the device. The OXC includes a chip, the chip including a plurality of input micromirrors and a plurality of output micromirrors; and a reflector optically coupled to the plurality of input micromirrors and the plurality of output micromirrors. The OXC package in accordance with the present invention folds the light beam during scanning. In the preferred embodiment, the OXC package comprises input and output micromirrors on a single chip. A reflector is placed above both the input and output micromirrors for folding the light beam as it travels between an input micromirror and an output micromirror. In the preferred embodiment, the distance from the input/output micromirror to the reflector is approximately one-half of the Rayleigh Length of the light beam. With the folding of the light beam in this manner, the input and output micromirrors may be placed in close proximity to each other, resulting in a smaller device.
