optical propagation loss

基本解釋

The measurements of optical-waveguide mode and propagation loss indicate that the film is of good optical waveguide properties with low loss.
膜表面粗糙度很小。光波導(dǎo)模式和光損耗測(cè)量表明膜具有較低的損耗。
The principles of the common methods to measurement the propagation loss of the NLO polymer film optical waveguide are summarized, and the typical experimental arrangements are presented.
