The powerful and significant thermal radiative effect opens up a new opportunity and method for route-asymmetrical light transmission. Above mentioned unique features can be mostly attributed to the significant characteristics of the thermal radiative effect, which could cause a fiber displacement up to tens of microns. The route-asymmetrical device has been demonstrated effectively with not only the continuous- wave (CW) light but also 10 Gbit/s on-off-keying (OOK) digital signals. Employing a fiber-chip-fiber optomechanical system, our scheme has successfully achieved a broad operation bandwidth of at least 24 nm and an ultra-high route-asymmetrical transmission ratio (RATR) up to 63 dB. In this paper, we proposed and experimentally demonstrated a route-asymmetrical light transmission scheme based on the thermal radiative effect, which means that forward and backward propagations of an optical device have different transmittances provided they are not present simultaneously.
