| dc.description.abstract | 近年來，矽光子晶片電路具備多功能運算能力受到許多關注，因為它符合下世代全光資料傳輸處理的迫切需求。在此論文中，我們利用了非對稱富碳碳化微共振腔實現TE/TM極化資料的解調、雙埠克爾開關與全光邏輯閘。
首先，利用最小波導截面的富碳碳化矽非對稱微共振腔增強了非線性克爾開關，設計當中考慮波導尺寸、對稱性對波導的影響，並優化了間距與錐狀反向波導結構。富碳碳化矽非對稱波導有較好的光侷限性，以及非線性折射率至.44×10-12 cm2/W，此外TE模態有較好的光侷限性與雙折射的特性。利用此優化的非對稱波導可提供有效非線性全光開光，並應用於未來晶片上光電元件上。 接著，富含碳-碳鍵結碳化矽雙埠共振腔可為多功能矽光子集成電路上應用。首先，利用極化選擇性的共振腔可實行12-Gbit/sTE/TM極化資料的解調；由於雙埠共振腔有互補的穿透譜，可應用於克爾開關，同時實現正相與反相資料轉換；另外由於極化相關的TE/TM穿透譜，雙埠共振腔也可應用於全光及邏輯閘。 最後，TE/TM極化相依的碳化矽環波導結構可用於加載於幫浦光源上的振幅鍵、相位偏移鍵間的全光及邏輯閘應用，僅當幫浦光源在開啟，與其極化平行於環波導的模態，偵測光源可被調變。 | zh_TW |
| dc.description.abstract | In past few years, the on-chip photonic circuits with versatile gating functionality has received more attention to meet urgent requirement of high-speed all-optical data transmission and processing on chip in the coming era. In his thesis, we demonstrated the asymmetric C-rich SixC1-x micro-ring with optimized waveguide structure for TE/TM polarized data decoding, dull-port Kerr switching and all-optical logic gates.
First of all, the smallest asymmetric channel waveguide with 500-nm width and 350-nm height based C-rich SixC1-x micro-ring for enhancing the nonlinear optical Kerr switching is demonstrated by carefully considering the effect of size and symmetry of channel waveguide and designing the gap spacing and the inverted tapper. The C-rich SixC1-x based asymmetric channel waveguide provides the tight optical confinement and strong nonlinearity of up to 2.44×10-12 cm2/W for efficient nonlinear optical Kerr switching. Furthermore, the asymmetric channel waveguide prefers the TE mode due to the better modal confinement and presents birefringent property. Such an optimized asymmetric channel waveguide based C-rich SixC1-x micro-ring serves an efficient nonlinear optical switching for the future on-chip optoelectronic devices. Afterwards, a C-C bond enriched SiC based add-drop micro-ring is utilized to demonstrate the multi-functional photonic circuits. Firstly, the asymmetric add-drop micro-ring with a polarization-selective property enables to implement the 12-Gbit/s TE/TM polarized data decoding. Furthermore, the transmission spectrum in the bus port is basically complementary to that in the ring port for the add-drop micro-ring, which demonstrates the dual-port Kerr switch for both data conversion and inversion at 10 Gbit/s. Owing to the different polarization-dependent transmission spectra on TE and TM modes, the add-drop micro-ring with asymmetric waveguide structure promises the all-optical AND gate application. Eventually, the TE/TM-mode spectral-separated C-rich SiC ring waveguide is employed to demonstrate polarization-dependent amplitude/polarization shift keying (ASK and PolSK) “AND” logic gate. Such a polarization dependent spectral notch can be utilized to perform the polarization-dependent all-optical AND gating. Only when the pump is set at ON state and the polarization of the pump is parallel to the corresponding notch of the ring waveguide throughput, the output of probe can be cross-wavelength modulated to provide the “AND” gating between the ASK and PolSK streams exactly. | en |
