2. Holographic optical elements (HOEs, volume gratings): All that HOEs including (i) theoretical analyses (analytical Fourier optic analyses & numerical calculations) (ii) holographic inscriptions/printing of various optical elements (lens, prisms, and data storages)(iii) advanced materials synthesis.
Why HOEs? there's a vast variety of fields, which can significantly benefit from HOEs (i.e., displays, spectroscopy, microscopy, micro/nano-optical components, AR/VR, holography, solar-energy devices, and so on).
A representative example is the AR/VR display evolution by using HOEs (more thin and lightweight VR glasses), which was reported by Meta Reality Lab (Facebook Reality Lab): ACM Trans. Graph. vol 39, No. 4, Article 67 (July 2020)

HOEs @ Korea University: recently, we have newly conceptualized an ideal HOE in terms of Fourier optics (i.e., optical Fourier volumes) and materialized them by advancing theoretical backgrounds and material aspects simultaneously.

Diffractive optical elements (DOEs, surface gratings): All that DOEs including (i) theoretical analyses (analytical Fourier optic analyses & numerical calculations) (ii) holographic inscriptions/printing of various optical elements (lens, prisms, and data storages)(iii) advanced materials synthesis.
Why DOEs? the surface counterparts of HOEs

DOEs @ Korea University: Our group @ Korea university enables the development of a wide-scale and perfect DOEs (sinusoidally modulated perfect surface grating in terms of Fourier optics, called optical Fourier surfaces) in an unprecedented throughput. More importantly, we very recently reached the theoretical upper bound of diffraction efficiency at the whole visible regime.
