Abstract
One example power equalizer includes an input/output assembly, a multiplexer/demultiplexer, a pre-attenuation component, and a light beam modulator. The multiplexer/demultiplexer demultiplexes a first light beam into a plurality of first sub-wavelength light beams including a particular sub-wavelength light beam, and propagates the plurality of first sub-wavelength light beams to the pre-attenuation component. The pre-attenuation component makes the particular sub-wavelength light beam incident onto the light beam modulator at a preset angle. The light beam modulator performs angular deflection on the plurality of first sub-wavelength light beams to obtain a plurality of second sub-wavelength light beams. The pre-attenuation component then propagates the plurality of second sub-wavelength light beams to the multiplexer/demultiplexer. The multiplexer/demultiplexer multiplexes the plurality of second sub-wavelength light beams into a second light beam.
