Wavelength Conversion Via Refractive Index Tuning of A Hexagonal Photonic Crystal Cavity

Résumé

Photonic crystals are consisting of a periodic dielectric medium that can affect the electromagnetic wave propagation by creating allowed and forbidden electronic energy bands. Bands of wavelengths which are not allowed are called photonic band gaps. An optical cavity can trap light at resonance frequencies and thus also be called as an optical resonator. By rapidly changing the cavity's resonance wavelength, it is possible to forcefully change the wavelength of photons captured in a cavity. It is achievable that the wavelength conversion of light across the simple dynamic refractive index tuning of a PC cavity. Our main purpose in this research is to find out which is the most beneficial material for optical converter. Applications like laser converters, coherent converters and opto-electronic converters are based on optically controlled gates are being highly researching for future use. The simulation process is done by FDTD solution method. This work aims at both developing highly nonlinear optical wavelength converter and demonstrating via cavity tuning through different types of material (silicon, GaAs, Germanium) at telecommunications wavelengths. We investigate the field intensity characteristics of wavelength-converted light. We used three different ways of cavity tuning and applied on three different material (Si, GaAs and Ge) to find out which one shows more better response. According to our result there is no noticeable peak at the original wavelength. After the simulation process, tuned through the cavity it shows that 100% wavelength conversion occurs in this process. Our results indicate that this wavelength conversion process can be noticed in clear eye. The significance of this research project is that it shows us a path to choose dielectric medium for future use.
