| Title | Design and Fabrication of High-Quality Factor (High-Q) Microring Resonators |
| Summary | This project focuses on the design and fabrication of high-quality factor (High-Q) microring resonators, which are essential components in photonic integrated circuits (PICs) for applications such as optical filtering, wavelength division multiplexing (WDM), sensing, and quantum photonics. Microring resonators are highly compact and efficient structures that enable precise control and manipulation of light, making them critical for advancing modern photonic technologies. The project is divided into two main phases. In the design phase, advanced simulation tools such as Lumerical FDTD and COMSOL will be utilized to model and optimize the microring resonator's geometry, material properties, and coupling mechanisms. Key design parameters, including ring radius, waveguide width, gap spacing, and refractive index contrast, will be carefully analyzed to achieve high-Q factors, low insertion loss, and optimal resonance characteristics. The simulations will also assess critical performance metrics such as free spectral range (FSR), extinction ratio, and thermal stability. In the fabrication phase, the microring resonator will be fabricated using state-of-the-art nanofabrication techniques. The process begins with the deposition of high-quality silicon nitride (SiN) or silicon-on-insulator (SOI) layers on a substrate, followed by patterning using electron-beam lithography (EBL) or deep ultraviolet (DUV) lithography. Reactive ion etching (RIE) will then be employed to precisely define the microring and waveguide structures. Post-fabrication, the device will undergo thorough characterization using optical testing methods such as transmission spectroscopy, optical microscopy, and scanning electron microscopy (SEM) to evaluate its performance and validate the design. The ultimate goal of this project is to develop high-Q microring resonators with exceptional optical performance, enabling their integration into next-generation photonic systems for applications in telecommunications, sensing, and quantum computing. By pushing the boundaries of design and fabrication, this work aims to contribute to the advancement of compact, efficient, and scalable photonic devices. |
