PhD Topic:
This Ph.D. research explores aluminum nitride (AlN) waveguides for supercontinuum generation, emphasizing their broad spectral coverage (200–3000 nm) and potential applications in spectroscopy, microscopy, and optical coherence tomography. AlN, known for its wide bandgap, high thermal conductivity, and strong nonlinear properties, enables efficient spectral broadening with high power-handling capacity. Compared to traditional media like photonic crystal fibers and silicon nitride waveguides, AlN offers superior phase stability and coherence, which are crucial for noise reduction and precision in optical applications. The study employs advanced simulation techniques, including nonlinear Schrödinger equations, to model critical nonlinear dynamics such as soliton formation and dispersive wave generation. Fabrication involves precise cleanroom techniques like sputtering and reactive ion etching to optimize waveguide geometry. This research advances AlN’s role in integrated photonics, enhancing its utility for high-resolution spectroscopy, optical waveform generation, and quantum technologies reliant on broad, coherent supercontinuum sources.
