寬隔波道
英文
wide-seperation channel-
The tbc algorithm simulates that wave near the boundaries is plane wave, and its amplitude and direction are decided by trial and error. in this thesis, the operation principle of an awg is introduced and the structure parameters of 8x8 awg with its central wavelength 1550. 12 / 7 / n and channel spacing 3. 2nm are designed by discussing the crosstalk to neighboring waveguide, the insertion losses and losses equal, etc. this thesis employs the waveguide theories to analyze the slab waveguide and the arrayed waveguide, and offers the distributions of stable optical fields
本文旨在設計一個中心波長為1550 . 12nm 、波長間隔為3 . 2nm的8 8awg波分復用器，通過綜合考慮相鄰波導間的最大串擾、插入損耗、通帶寬度以及各通道損耗均勻等指標來設計、優化awg的各個結構參數，如輸入、輸出波導和波導陣列中相鄰波導的間隔，平板波導的聚焦長度，波導陣列中相鄰波導的長度差等。The millimeter wave diplexers used in the ka - band satellite communications are investigated. these diplexers are of high working frequency, narrow passband and high selectivity, which demands the channel filters good performance
所研究的毫米波雙工器工作頻率高（接近40ghz ） ，收發通道帶寬窄、接收頻率和發射頻率間隔很小。The interleaver with channel spacing of 50ghz is designed and prototype device is achieved. we test experimentally the interleaved spectrum in the c - band which is rectangle with ripple of less than 0. 1 db. and through measuring its time delay, we obtain the character of its dispersion. a novel architecture of 50ghz mfpi interleaver with different passband widths is put forward at first
2 、設計了通道間隔為50ghz的mgti型interleaver濾波器，獲得了該濾波器的原型器件；實驗得到了該器件在c波段兩組交錯分波的矩形化光譜，其紋波小於0 . 1db ，通過對器件時延的測量，間接獲得了其色散特性；首次提出mfpi型不等帶寬50ghz的interleaver濾波器技術方案。
