A multi-channel mode converter (100) includes a lens array (110) having a first lens and a second lens, a glass block (120) coupled to the lens array (110), and a fiber assembly unit (FAU) array (130) coupled to the glass block (120), the FAU array (130) including a first fiber (140) corresponding to the first lens (165), and a second fiber (140) corresponding to the second lens (165). The FAU array(130) provides for a corresponding number of fibers (140) and lenses (165) such that a specific single fiber (140) corresponds to a specific single lens (165), there being a 1: 1 relationship between fibers (140) and lenses (165). A mode converter system (600) comprises: a lens array(110) comprising: a first silicon lens (165) configured to convert a first mode between a first waveguide (620) and a first fiber (140), and a second silicon lens (165) configured to convert a second mode between a second waveguide (620) and a second fiber (140), and a glass block(120) coupled to the lens array(110) and configured to provide an optical path for a first light beam corresponding to the first silicon lens (165) and a second light beam corresponding to the second silicon lens (165).
