In order to realize compact all-optical devices, thinning of chalcogenide optical waveguides with a high nonlinearity was experimentally demonstrated. We were able to fabricate wire-waveguides with a rectangular core using electron beam lithography. However its yield rate was very low because some parts ofa dielectric core came off owing to small contact area between the core and the substrate. Therefore microring resonators with multimode interference (MMI) couplers were fabricated using strip-loaded waveguides, where its adhesion is increased.The linear and nonlinear properties of fabricated devices were examined at a wavelength of 1.06 μm. Unfortunately, optical bistability in the microring has not yet been observed. In relation to the development of these nonlinear devices, the dynamic behavior of ring resonator with fast and slow (cumulative) optical nonlinearities was theoretically investigated using a novel iterative method. Moreover the cw response and pulse response of a nonlinear MMI coupler were investigated using the beam propagation method and coupled-mode theory, respectively and many useful insights were obtained.

为了实现紧凑型全光器件，实验研究了高非线性硫族化物光波导的减薄。我们能够制造线波导与矩形芯使用电子束光刻。但由于介质芯与衬底接触面积小，部分介质芯脱落，成品率很低.因此，我们采用条形加载波导制作了带多模干涉耦合器的微波谐振器，增加了波导的粘附性，并在1.06 μm波长下测试了器件的线性和非线性特性。不幸的是，微环中的光学双稳态尚未被观察到。针对这些非线性器件的发展，采用一种新的迭代方法，对具有快、慢（累积）光学非线性的环形谐振腔的动态特性进行了理论研究。此外，分别用光束传播法和耦合模理论研究了非线性MMI耦合器的连续波响应和脉冲响应，得到了许多有用的结论。
