Entangled photon pairs whose temporal correlation width are single optical cycle can be used in many applications including an enhancement in the rate of two-photon absorption and sum-frequency generation. However, a temporal width of the broadband entangled photons generated from a chirped quasi-phase-matched device is broadened by the effect of dispersion caused by optical components in the optical paths. Therefore, the dispersion control of the entangled photons is necessary for minimizing the temporal correlation. We report the designing of a biphoton compressor that consists of a spacial light modulator which is able to cancel the higher order dispersion and a prism pair. We also report numerical simulations of temporal correlation width obtained by our designed compressor.
