Nonlinear optics and hybrid integrated photonics

(24h, 3 ECTS)

Nonlinear optics. This course aims at introducing the physics of nonlinear optical effects and the major developments of this discipline. It is a necessary complement to telecommunication optics, optical signal processing, and photonics components, courses.

Program

  1.  Introduction to nonlinear optics,
  2. Second-order nonlinear effects,
  3. Third-order nonlinear effects,
  4. Nonlinear optics for biology, in particular multiphotonic microscopy.


Integrated photonics and nano-photonics devices by hybrid and coupled thin layer process. The goal of such micro- and nano-photonics course is to present integrated photonics and materials with a view to highlight the recent development of specific hybrid processes (such as biomolecular film deposition, assembled growth and handling of optical elements, plasma treatments coupled with microtechnologic thin layers processes, and microfluidic devices) for the realisation of optical components devoted respectively to sensors (physical, chemical, biologic measurements) and to optical telecommunications applications.

Program:

 

  1.  Introduction to integrated photonics, overview,
  2. Theory of advanced electromagnetic waveguides,
  3. Micro-photonics components and hybrid process for sensors and optical telecommunication applications,
  4. Nanophotonic / sub-wavelength photonics by coupling hybrid thin layer process: Examples of photonic structures based on photonic crystals (filters, detectors, VCSEL)..

 

Integrated and Microwave Optics

(24h, 3 ECTS)

Integrated optics. Introduction to integrated optics; Ray optics of optical fibers and planar waveguides; Guiding conditions; Modes; Maxwell equations with specialization to planar and cylindric waveguides; Exact solutions; Approximate solutions based on Gaussian modes; Examples of measurements and applications of guided modes (MLines, plasmons, couplers with mode adaptation…); Coupled waveguides and coupled-waveguide-based components: Bragg mirrors, optical couplers, electro-optic modulators, DFB lasers, 1D photonic crystals.

Microwave photonics. This course gives an introductory approach to the specificity of analog transmissions on optimal carriers, compared with digital optical transmissions. The toolbox to modelize such analog transmissions are presented, together with the ways of choosing the optical components. Recent techniques of all-optical delivery and treatment of analog signals in the RF and microwave domains are shown.

The three parts of this course are:

  1. Microwave photonic links
  2. Optical delivery and treatment of microwave signals
  3. Conception and optimization of microwave optical links
