Minghao Qi

Minghao Qi is a Professor in the Department of Electrical and Computer Engineering at Purdue University's College of Engineering, West Lafayette. His research focuses on integrated photonics systems for optical communications, quantum information, and precision metrology applications.

Professor Qi's work spans several critical photonics domains:

• Design and application of microresonator-based optical frequency combs (Kerr combs)
• Silicon and silicon nitride integrated photonic circuits
• Thin-film lithium niobate devices for nonlinear optics
• Quantum information processing using frequency-bin entangled photons
• Photonic neuromorphic computing with machine learning co-design
• Optical sensors and time-of-flight ranging systems

Analysis of his 2022-2025 publications reveals three dominant research vectors: (1) Vernier microcombs for optical atomic clocks and RF stabilization, (2) Trident edge coupler architectures for octave-spanning nonlinear processes on lithium niobate, and (3) Physics-informed neural networks applied to photonic device design and signal processing. His recent work demonstrates strong convergence between integrated photonics, quantum technologies, and machine learning.
