Problems solved by technology

With the improvement of technology and structure, the transmission loss of nanowire waveguides is continuously reduced. At present, there are reports of nanowire waveguides with losses less than 3dB / cm. Although the value is relatively large, the device area based on nanowire waveguides is small, so The overall transmission loss of the device is not large
