Course details

The course offers a comprehensive introduction to the three key pillars of future photonic technologies, namely nanophotonics, plasmonics, and metamaterials, covering both their fundamental concepts and recent advancements. It discusses the basic and applied aspects of nanophotonics, focusing on the control, guidance, and manipulation of electromagnetic radiation at the nanoscale. The course begins with the principles of photonic crystals, metal optics, and surface plasmon resonance along with their applications. It then moves on to metamaterials and metasurfaces, explaining their fundamentals and a wide range of applications such as tunable devices, absorbers, hyperlenses, superlenses, beam steering, cloaking, and transformation optics. In addition, the course introduces alternative materials used in nanophotonics and provides an overview of various fabrication techniques for nanophotonic devices.

Questions and Answers

Q: You're on-site doing optical acceptance for a gold nanorod array sensor, and you're googling "how to verify plasmon resonance wavelength shift during on-site acceptance test". The subcontractor reports a 12 nm red-shift after functionalization. Before you sign the ITP, what do you verify first, and against what criterion?

Q: Design review for a subwavelength waveguide, and you're searching "best metal for low-loss plasmonic waveguide at telecom wavelength". The device must operate at 1550 nm with minimal propagation loss and survive a 125 °C HTOL. What do you select?

Q: During concept sizing you're typing "estimate field enhancement factor in plasmonic nanoantenna". A bowtie antenna has a 10 nm gap and is illuminated at resonance. What's a defensible order-of-magnitude electric field enhancement in the gap?

Q: You're doing pre-commissioning on a negative-index metamaterial slab and googling "metamaterial refractive index verification conflicting S-parameter measurements". Free-space VNA extraction gives n = −1.2, while waveguide-based extraction gives n = −0.6 at the same frequency. What's your next move before accepting the data?
