Multiplexed transmission by optical beam transformation

A method of transmission supporting multiplexed communication by optical beam transformation, the method comprising:

• generating a first beam having a first frequency in an optical frequency range;
• generating a second beam including data and having a second frequency in the optical frequency range;
• converting the first beam and the second beam into a third beam including the data and having a third frequency based on a difference between the first frequency and the second frequency;
• and
• transforming the third beam into a fourth beam having a first angular distribution and including a first portion of the data, and into a fifth beam having a second angular distribution corresponding to the first angular distribution and including a second portion of the data.

A system of transmission supporting multiplexed communication by optical beam transformation, the system comprising:

• a transmitter system comprising:
• a first beam generator to generate a first beam having a first frequency in an optical frequency range;
• a second beam generator to generate a second beam having a second frequency in the optical frequency range;
• a beam modulator operatively coupled with the second beam generator to modulate the second beam to include data;
• an optical fiber operatively coupled with the first beam generator and the beam modulator to convert the first beam and the second beam into a third beam including the data and having a third frequency based on a difference between the first frequency and the second frequency;
• and
• a phase transformer operatively coupled with a photodiode to transform the third beam into a fourth beam having a first angular distribution and including a first portion of the data, and into a fifth beam having a second angular distribution corresponding to the first angular distribution and including a second portion of the data;
• and
• a receiver system comprising:
• a second phase transformer to receive the fourth beam and the fifth beam;
• an optical signal converter to transform the fourth beam and the fifth beam into a sixth beam in the optical frequency range including the first portion and the second portion of the data;
• and
• a digital signal processor to generate, based on the sixth beam, a first electrical signal including the first portion and the second portion of the data.
