 Metasurfaces Plasmonics Photonic crystals

In this course we will learn how to tailor light-matter interactions by confining light and emitters to nanometer length scales. Through lectures, review articles, and hands-on use of Lumerical (industry standard nanophotonics simulation tool provided for free during the semester), we will learn how to design and simulate structures exhibiting, for example: 
  • Fluorescence enhancement of an emitter embedded in a photonic crystal cavity
  • Plasmonic resonances in metallic nanostructures.
  • Phase/polarization control of light using dielectric nanopillars
Along the way we will learn about applications of these and other phenomena that are being pursued by nanophotonics researchers in academia and industry with a special emphasis on applications in biomedical imaging and sensing. 

The course is structured as follows:
  1. Review of E&M theory: Maxwell’s equations, wave equations, modes, intro to plasmonics, and fundamentals of computational techniques. 
  2. Lumerical tutorial, commercial electromagnetics simulation tool
  3. Case studies (3 total). We will study in depth three topics in nanophotonics: photonic crystals, dielectric metasurfaces, and plasmonics. For each topic, we will have a guest lecture from an active researcher in the field: UNM Prof. Stavroula Foteinopoulou (Photonic Crystals), Sandia scientist Dr. Adam Backer (Metasurfaces), and UNM Prof. Alejandro Manjavacas (plasmonics). Next, we’ll have a literature review, where students will present and discuss a related review article. Finally, we will have a computer lab, where we will collaboratively design and simulate (with Lumerical) nanophotonic structures related to the topic. 
  4. Student presentations. In place of a final exam, students will perform a case study on a nanophotonics topic of their choice. They will use Lumerical and/or other forms of analysis to investigate the topic, and they will present results in an oral presentation to the class.
Assignments and grading policy:
The purpose of this class is to learn about nanophotonics and have some fun along the way, not to stress about grades. The primary purpose of grading assignments is to give students feedback on their work. The final course grades are scored on a curve, and students usually get an A or A- if they complete all assignments. 

Assignment 1: Photonic Crystals: design a cavity. (20% of total grade)
Assignment 2: Plasmonics: design a nanoparticle. (20%)
Assignment 3: Dielectric metasurfaces: design a half waveplate.  (20%)
Assignment 4: Final Exam presentations, Wed, Dec 11, 4 - 6:30 pm, Regener 118. (20%)
Participation: includes attendance, lit review, final project synopsis. (20%)

Assignments 1-3 are completed by pairs of students. Students submit one assignment per pair, and one grade is given to the pair. Students are encouraged to switch partners for each assignment. If a student prefers to work alone on the final project, they may do so. Else they can work in pairs, and one grade will be given to the pair.

Late policy on Assignments 1-3: Completed assignments are due 
via email (victormarcelacosta@gmail.com) at the beginning of class on the designated date listed in the class schedule. Assignment scores will be reduced by 5 points (out of a total of 100) for each week late. For example, completed assignments submitted between 1 hour to 7 days late lose 5 pts, 8-15 days late lose 10 pts, etc.  The final project is an in-class oral presentation--if you foresee a scheduling conflict please contact the instructor ASAP.

Literature Reviews:
Pairs of students will deliver a literature review on a paper of their choice. Everybody will have a chance to present once. The paper will be selected 1 week prior to class and the entire class is required to read the paper and come with at least one question to ask. Grades will be credit/no credit.
