A 1 × 4 3D broadband polymer optical waveguide switch matrix is demonstrated. The fabricated device, which contains four vertically coupled thermo-optic switches, has a compact construction (only 9 mm in length) and a power consumption of 45 mW . Compared with the corresponding planar ones, this 3D switch matrix has two distinct features. First, the light signal can be easily switched to any output port by operating only a single switch unit. Second, the switching extinction ratio, cross talk, and insertion loss of this matrix are practically wavelength independent over the whole C band. We also show that this structure can be extended quite simply to an M × M nonblocking switch matrix.
