Course description

INTRODUCTION:

challenges and trends in the field of photonics latest achievements – what of these we will learn, today in tomorrow of nanophotonics, why to use a photon instead of an electron

 

LIGHT:

light and Maxwell – electromagnetic waves, light and matter, optical situation at an interface of two media, light interaction with nanometer size structures, Fourier optics – why?, electro-optical and magneto-optical effects and components

 

PHOTONIC COMPONENTS:

operational principles, design and technologies, use in photonic circuits:

  • photonic crystals: 1D, 2D, 3D,
  • metallic nanostructures: metamaterials, negative refractive index, plasmonic effects
  • resonators, filters and modulators
  • micro and nanolasers
  • micro fotodetectors
  • attempts towards optical transistors

 

PHOTONIC INTEGRATED CIRCUITS (PICs):

photonic electronic integration – why?, latest examples of integration of above mentioned photonic components in PICs, platforms on Si on insulator, InP material and TriPleX, design tools, examples of design, practical cases, towards optical gates, how to proceed and what is restricting us on the way towards optical computers

 

FIBER  SENSORS:

interferometric, photonic crystal based, liquid crystal based, plasmonic detection, use in biomedicine and in other fields

 

NANOPHOTONIC STRUCTURES IN PHOTOVOLTAICS:

antireflection structures, light management photonic structures in solar cells, novel reflectors, practical design and characterisation of nanophotonic structures, design based on 3D optical modelling (FEM, FDTD, RCWA), characterisation methods and instruments, measurements of reflection/transmission, light scattering, angular distribution function)

Objectives and competences

The objectives of the course are to familiarize students with the state-of-the-art knowledge on photonics, especially on integrated photonics. We focus on integrated photonic circuits, fiber sensors and nanophotonic structures in photovoltaics. Students will learn theoretical background and practical issues in the design and application of the photonic devices.

Learning and teaching methods

The lectures provide a theoretical background on nano(photonic) structures, practical examples are shown. In the practical work students will focus on design of simple photonic integrated circuits. They will also measure characteristics of selected (nano)photonic structures. A part of the educational process will be carried out by means of ICT technologies, employing options they offer.

Intended learning outcomes

After successful completion of the course, students should be able to:

  • explain operational principles of presented nanophotonic structures.
  • specify the meaning and possible application of basic components in photonic integrated circuits (PIC).
  • categorise different technologies of PICs and to describe their pros and cons.
  • design simple PICs
  • measure selected characteristics of. nanophotonic structures.
  • analyse different realizations of optical fiber sensors.
