Abstract
A photon source for quantum communication including a plurality of optical channels, each comprising: a light emitter configured to emit optical pulses, and a phase mask optically connected to the respective light emitter and configured to encode an orbital angular momentum into incident light, wherein each of the phase masks of each optical channel is configured to encode a mutually orthogonal orbital angular momentum to the optical pulses emitted by the light emitter of each optical channel to provide an encoded optical output; a controller electrically coupled to each light emitter in each optical channel and configured to control parameters of the optical pulses; and combining optics configured to combine the encoded optical output of each of the optical channels to form a single encoded optical signal.
