Research Interests

Patrick works on the application of adaptive optics to laser micro-fabrication. He uses femtosecond pulse lasers to manufacture three dimensional devices inside transparent materials, applying adaptive optical techniques to enhance precision and/or speed. 

Areas of particular interest are devices inside diamond; engineering for quantum technology; liquid crystal photonics; and microscope calibration.

Current Projects

DiATOM  Diamond in Advanced Technology through Optical Machining

M2I2 Multiscale multidimensional integrated imaging for precision laser processing

Programmable volume photonics
