【摘要】：使用集成光學制備工藝的光波導延遲線的延時精度能夠達到亞皮秒量級,能夠滿足雷達對工作頻率越來越高的要求。而相對于無機材料而言,近年來有機聚合物光集成器件因其特有的優(yōu)勢,越來越成為熱門的研究課題。聚合物材料在制作光波導時,具有成膜性好,剪裁性和加工性強,以及與襯底的兼容性高的優(yōu)點。同時,在光的損耗,折射率的控制,熱穩(wěn)定性等性能方面的實驗和進展表明,聚合物將成為低成本,高性能的光集成器件的基礎材料。本論文首先對平板光波導理論以及陣列波導光柵的工作原理進行了詳細的研究。并以光波導理論和光的耦合模理論為基礎,根據(jù)AWG的工作原理和各參數(shù)特性。設計出了工作于通信波長的1×8陣列波導光柵,并用Rsoft軟件進行了模擬和參數(shù)的優(yōu)化。然后根據(jù)制作所需的流程,對制備工藝進行了詳細的探究和分析,得出了完整的工藝流程和參數(shù)。選用了ZPU13系列的有機聚合物作為波導的芯層和包層材料。制備出了波長間隔1.6nm的1×8陣列波導光柵并進行了測試。測試結果表明器件成功實現(xiàn)了對中心波長為1550nm的輸入光的波分復用功能,平均波長間隔為1.6nm,插入損耗小于-20dB,3dB帶寬1nm,符合設計的預期效果。接著通過進一步優(yōu)化AWG的設計,單片集成AWG及延時線陣列,制備出了具有光學真延時效應的2bitAWG基光學真延時線,波長間隔為1.6nm。輸出的四種波長分別具有0ps,40ps,80ps,120ps的延時量。證明了設計方案的可行性,為下一步集成光學真延時系統(tǒng)研究奠定了基礎。
[Abstract]:The delay precision of the optical waveguide delay line using integrated optical fabrication process can reach sub-picosecond order, which can meet the increasing requirements of radar operating frequency, but compared with inorganic materials. In recent years, organic polymer optical integrated devices have become more and more popular research topics because of their unique advantages. Polymer materials have good film formation, good tailoring and good processability when making optical waveguides. At the same time, experiments and advances in optical loss, refractive index control, thermal stability and other properties show that the polymer will become low cost. The basic materials of high performance optical integrated devices. Firstly, the theory of planar optical waveguide and the working principle of arrayed waveguide grating are studied in detail, and based on the theory of optical waveguide and the coupled mode theory of light. A 1 脳 8 arrayed waveguide grating working at the communication wavelength is designed according to the principle of AWG and the characteristics of each parameter. Rsoft software was used to simulate and optimize the parameters. Then according to the process of production, the preparation process was studied and analyzed in detail. The complete technological process and parameters were obtained. The ZPU13 series of organic polymers were selected as the core and cladding materials of the waveguide. 1 脳 8 arrayed waveguide gratings with a wavelength interval of 1.6 nm were prepared and carried out. The test results show that the device has successfully realized the wavelength division multiplexing function of the input light with a central wavelength of 1550nm. The average wavelength interval is 1.6 nm, and the insertion loss is less than -20 dB Bu 3dB bandwidth 1 nm, which is in line with the expected effect of the design. Then, the design of AWG is further optimized. Two bit AWG based optical true delay lines with optical true delay effect have been fabricated by integrating AWG and delay line array. The wavelength interval is 1.6 nm. The four wavelengths of the output have 0 PS respectively. It proves the feasibility of the design scheme and lays a foundation for the further research of integrated optical real delay system.
