1. An optical system for controlling atoms, the optical system comprising:
a laser source generating a laser beam at a carrier frequency;
a modulation signal module comprising a microwave (MW) frequency source generating a MW signal at a first frequency, and a radio frequency (RF) source generating a RF signal at a second frequency, the RF frequency and the MW frequency together defining a set of frequencies, the modulation signal module further configured to generate I and Q modulation signals at the set of frequencies; and
an IQ modulator configured for receiving the laser beam and the generated I and Q modulation signals at the set of frequencies and for outputting an output laser beam based on the received laser beam and the generated I and Q modulation signals at the set of frequencies, wherein the output laser beam comprises multi-toned optical single-sidebands (MT-OSSB) offset from the carrier frequency by the set of frequencies and wherein the carrier frequency is suppressed.
