While the radio spectrum continues to struggle with a soaring bandwidth demand, the optical spectrum promises virtually unlimited license-free bandwidth. We report the feasibility of high-capacity point-to-point links for indoor optical wireless communication with cascaded diffractive optical elements (DOEs) for free-space optical beam-steering. An investigation of such optical wireless transmission has been carried out in an experimental testbed.
