摘要
A novel data transmission scheme that can be used for any desired transmitting direction in free space is introduced. This scheme is obtained by analyzing the analytic form of the diffracted spectrum of a coherent broadband Gaussian spectrum incident on a shifting double slit. The merits of this method are that the transmission angle can be chosen arbitrarily in advance and that it is easy to implement compared with other previous schemes which modulate some properties of the light source.
