Abstract


Dense Wavelength Division Multiplexing (DWDM) optical network is the inevitable trend of the development of optical communication tunable filter development plays an important role in the development of all-optical dense wavelength division multiplexing network; photonic crystal The research is a new direction for the development of the field of optics, super prism \In order to adapt to the requirements of the development of optical network wavelength division multiplexing devices based on liquid crystal electro-optical properties of tunable method - Perot cavity narrowband filter based on multilayer interference the super prism dispersion of optical thin film WDM filter pieces, from the theoretical and experimental The two aspects of the system: the thesis the device film structures based on electro-optic tuning LCD Act - Perot interference filter (LCFPF), the combined effects of the device tuning performance. Found that in the process of continuous tuning of this type of tunable filters, interference level times, the transmission peak wavelength with a refractive index change monotonously; monotonic tuning is destroyed when the large change in refractive index causes the fringe order is changed, in the same transmission peaks jump \Several monotonic tuning programs; when the cavity thickness of 10 μm, a refractive index difference of 0.05 can make the monotonic tuning range of the device reaches the entire C-band. Through numerical simulation, and analysis of the reflection phase shift the LCD method Perot cavity (FP cavity) tuning performance. Finally, the main performance indicators of the device, experimental evaluation and optimization program for filter loss and bandwidth requirements. Use the super prism dispersion theoretical simulation and analysis of film characteristic matrix method of conventional λ / 4 film heap resonator structure film stack. Design and build a \Design and experiments show that considerable \on the metal reflector, although dispersion-shifted slightly decreases, the reflected light intensity has been increased, but also by multiple reflections to increase the dispersion-shifted; FP cavity structure of the membrane reactor, although the bandwidth is relatively narrow, but it can produce up 65μm dispersion-shifted and dispersion close to linear, having greater color resolution than traditional grating or a prism element. The thesis work has shown that the application of optical thin-film technology has the potential to construct functional devices with even more bizarre characteristics of optical thin film can be applied to different occasions.
