    Optical modules that support beam splitting

    Beamsplitters are optical components used to split input light into two separate parts. In the application scenario of beam combining, different beams overlap in both near-field and far-field spaces and are synthesized into a single aperture light source output. Top-Hat Beam Shapers convert a single mode beam into a uniform intensity beam of any desired shape and size. For multi mode beams, we offer Diffractive or. This paper reviews the on-chip beam splitting methods in recent years, which are mainly divided into the following categories: y-branch, multimode interference coupling, directional coupling, and inverse design.
