We propose a compact multi-channel 90゜ optical deflection device for short-distance optical interconnection. The device consists of stacked bent multimode optical waveguides having reflecting mirrors with bending angles of 90゜. The structure of the bent multimode optical waveguide with a bending angle of 90゜ was designed by ray-tracing simulations. The simulated insertion loss for each channel of the device was 0.5dB. We also propose a simple fabrication process using a pair of multi-channel linear optical waveguides with symmetrical 45゜ mirrors. An 8-channel 90゜ optical deflection device was fabricated using polymer materials and basic operation was confirmed. Our device has good potential for use as a high-density optical interconnection device.
