1. A beam steering system, comprising:
a tunable light source configured to direct a wavelength-swept beam;
an array of emitters, wherein
a first emitter of the array of emitters is configured to selectively emit a first beam at a first wavelength, the first wavelength is a portion of wavelengths of a first wavelength-swept beam, and
a second emitter of the array of emitters is configured to selectively emit a second beam at a second wavelength, the second wavelength is a portion of wavelengths of a second wavelength-swept beam and is different from the first wavelength; and
an optical device, arranged along a path of the first beam and the second beam, the optical device configured to receive the first beam and the second beam and to direct the first beam at a first angle and the second beam at a second angle into an external environment of the beam steering system.
