Thank you all for attending. Attached is the presentation slides from the session.
Also, below are some useful links to the examples used in the session, as well as a bonus article about OFH (Optically Fabricated Holograms)
Simulating diffraction efficiency of a volume holographic grating using Kogelnik’s method
Simulating diffraction efficiency of surface-relief grating using the RCWA method

Cheers!
This is seriously good stuff Kats. Well done to you, Michael, Alistair, Heng and any others involved!
