Claim 17:
18. A method, wherein the method comprises:
transmitting, using a first port of a port assembly of an apparatus, a third light beam to a first lens in a lens assembly of the apparatus corresponding to the first port, wherein the first lens comprises a zoom lens;
using the first lens, adjusting a width of the third light beam to obtain a fourth light beam, and transmitting the fourth light beam to a reflective element of the apparatus;
reflecting, using the reflective element, the fourth light beam to a dispersive assembly of the apparatus;
using the dispersive assembly, decomposing the fourth light beam into a first plurality of sub-wavelength light beams, and transmitting the first plurality of sub-wavelength light beams to the reflective element;
reflecting, using the reflective element, the first plurality of sub-wavelength light beams to a spatial light modulator (SLM) of the apparatus;
using the SLM, modulating the first plurality of sub-wavelength light beams, and reflecting at least one modulated sub-wavelength light beam to the reflective element;
reflecting, using the reflective element, the at least one modulated sub-wavelength light beam to the dispersive assembly; and
using the dispersive assembly, multiplexing the at least one modulated sub-wavelength light beam, and transmitting a multiplexed light beam to the port assembly through the reflective element and the lens assembly.
