Micro-fluid Channel Based on Ultralow-loss Silicon Crossing Waveguide for Various Sensing

We experimentally demonstrate a new type of micro-fluid channel design with crossing optical waveguides that not only block any gaps in the microfluidic channels in one fabrication step but also enable nearly lossless optical propagation in the primary waveguides on a chip. Such designs are critical for all sensing applications where the analyte must be flowed over the sensor.
