Metasurface holograms (meta-holograms) are subwavelength structures that have the
ability to control the properties of light opening up possible applications for
compact, high-resolution wavefront engineering. Such structures
allow for the tailoring of the shape of light for imaging and optical
trapping of sub-micron to micron-sized particles.
The student will be involved in one or more of the following:
1). Design and/or fabrication of the metasurfaces(@DTU Nanolab). Here, the student will learn basic FDTD modeling and computational Fourier optics to design the meta-holograms. The student can also be trained to implement cleanroom processes (e.g. ALD, dry etch) to fabricate the meta-holograms.
2). Characterizationof the metasurfaces:The student will carry out various characterization techniques –spectroscopic (transmittance and reflectance), ellipsometry and imaging (optical –bright field and phase contrast, SEM). The student will learn basic optical setups (2f or 4f optical setups, interferometry) for testing the performance of the metasurfaces.
