毫米波的过模准光传输损耗低、功率容量高。本文讨论了毫米波过模准光传输系统的损耗、功率容量,特别是模式激励等问题,推荐了在毫米波和亚毫米波频段可资应用的过模准光波导系列,并介绍了在8毫米频段上所得到的实验结果。 Millimeter-wave over-standard optical transmission loss is low, high power capacity. In this paper, the problems of loss, power capacity and especially mode excitation of millimeter-wave over-mode optical transmission system are discussed. The over-mode optical waveguide family which is available in the millimeter-wave and sub-millimeter-wave frequency bands is recommended. Millimeter band obtained on the experimental results.
