在本論文中,主要目的為研究利用偏折埋藏式波導結構所設計之可調變光衰減器。此衰減器所使用之結構乃為二次偏折結構,分為三個波導部份,而於分開處即偏折處插入兩個微稜鏡(microprism)區間使光偏折。
元件衰減原理是基於材料的熱光效應(Thermo-optical effects),在斜邊部份導光材料折射係數的改變會影響於其中之光場傳播方向進而達到衰減輸出的目的,詳細的理論模擬部份已由BPM-CAD計算完成。此外,在實驗部份已完成二次偏折波導之製作以及各角度的損耗量測。其針對1.3mm的波長量測得到的結果為,在經由兩次10度偏折後仍然可以保有65.7%的效率;而埋藏式通導結構波導所量得的傳輸損耗為0.48dB/cm。
A novel variable optical attenuator based on buried polymer waveguides and waveguide bends is proposed. The attenuator consists of three waveguide sections, separated for waveguide bending by two embedded micorprisms.
The attenuation of device was achieved by steering the beam propagation direction in the waveguide by thermo-optical effects. Detailed simulation results using the Beam Propagation Method are presented. In addition, radiation losses of the waveguide bends are experimentally investigated. After two-10° bends, the normalized insertion losses as low as 65.7% are obtained. The propagation loss of the buried waveguide is 0.47dB/cm at l=1.3 mm.
