The increasing of single channel capacities and evolution of optical networks topology , from simple point - to - point to intelligent optical networks , call for strict demands to optical filters . in this paper , the crucial technologies of optical filters such as interleaver , optical digital filter , fused biconical taper all - wave coupler as well as polarization - pump combiner have been studied experimentally and theoretically , which include : 1 . a new process , cascaded fbt ( fused biconical taper ) with precise control as well as strict interference arm length difference , is proposed for the first time to our knowledge 單信道速率不斷提高以及網(wǎng)絡拓撲由單一的點對點傳輸向可上下載的環(huán)網(wǎng)和可動態(tài)選擇波長路由的智能型格形光網(wǎng)絡演進,對光濾波器的常規(guī)性能指標、時域特性和動態(tài)可調(diào)諧特性提出了更加苛刻的要求,鑒于此,本論文全面研究了全光纖熔錐型奇偶交錯濾波技術、數(shù)字光濾波技術、基于g - t全通濾波器的奇偶交錯濾波技術以及熔錐型全波耦合器和偏振泵浦合波器。
all-wave meaning:[Electronics] Pertaining to a wide operating-frequency range. Few systems are literally all-wave. For example, a so-called “all-wave radio receiver” might cover 500 kHz to 30 MHz only. all-wave перевод:радио всеволновый
