It can be expected that fabry - perot filters and fiber grating filters will still play important roles in future all optical communication systems 它們的應(yīng)用將大大推動(dòng)高速光通信的發(fā)展,在未來(lái)的全光通信系統(tǒng)中仍將扮演重要的角色。
The mechanical tunable grating filter is realized by a grating and a rotary section . the angle between the incident light and grating is the decisive factor of the transmit wavelength 如:機(jī)械調(diào)諧的可調(diào)光柵濾光片,光柵安裝在一個(gè)旋轉(zhuǎn)部件上,光柵與入射光的夾角決定了所需要選擇的波長(zhǎng)。
Using the couple mode theory , the reflection spectrum , the peak reflectivity and the reflection bandwidth of several typical fiber grating filters have been theoretically analyzed and numerically simulated 數(shù)值模擬了它們的反射譜分布、峰值反射率以及反射帶寬隨光纖光柵的長(zhǎng)度和光柵折射率的調(diào)制深度的變化關(guān)系。
Being key components of optical fiber communication , fabry - perot filters and fiber grating filters have been applied in optical sources , wdm multiplexing and de - multiplexing , and add - drop multiplexing , wavelength routers , optical switching of all optical network etc . , which greatly promote the advance of high . speed optical communication technology 而法布里-珀羅濾波器和光纖光柵濾波器是現(xiàn)代光通信系統(tǒng)中的關(guān)鍵器件,它被廣泛應(yīng)用于光纖通信的各個(gè)關(guān)鍵環(huán)節(jié),從光源、波分復(fù)用的分波和合波,到全光網(wǎng)絡(luò)的上下路、波長(zhǎng)路由;光交換等。
