AIMS
The aim of this module is to examine the advance of optical techniques into
electronic systems for computation and communications. Two dimensional and
three dimensional transmission, storage and processing of information
using free space optics are discussed. Applications such as computer generated holography, optical correlation and optical switching are highlighted through the use of liquid crystal technology.
LECTURE SYLLABUS
Fourier Holograms and Correlation (6L, Dr T.D. Wilkinson)
- Fourier Transforms and
Holography introduction and motivation;
- Fourier transforms:
theoretical and with lenses: resolution of optical systems;
- Correlation and convolution
of 2-dimensional signal patterns;
- Dynamic and fixed phase
holograms.
Electro-Optic Systems (6L, Dr T.D. Wilkinson)
- Free space optical components; wave plates and Jones matrices
- Spatial light modulation
and optical systems;
- Shadow routing crossbars
and the perfect shuttle interconnect; Holographic crossbars;
- Wavelength filters and routing systems
- Smart pixels and optical
processing;
- The BPOMF and 1/f JTC correlators.
Optical Waveguide Technology (4L Dr. A. Georgiou)
- What is an optical waveguide - a simple definition
- Simple raytracing of waveguides
- Maxwell and the wave equations - a 'light' introduction
- Single mode and multimode structures
- Slab and fibre waveguides
- Key operational parameters for selected applications
- Principle technologies in use today - glass, e/o crystals, polymers and photonic crystals
Demonstrations in the lectures will include:
- 2D Fourier transform and
diffraction patterns
- Computer generated hologram
for optical fan-out.
- Optical beam steering with
dynamic holograms on SLMs.
OBJECTIVES
On completion of the module students should:
- Appreciate the derivation
and application of diffraction and Fourier optics;
- Be able to apply Fourier
techniques to simple optical spatial patterns;
- Understand the principles
of optical correlation and holography;
- Be able to explain the
principles and construction of spatial light modulators (SLMs);
- Appreciate the application
of SLMs to parallel processing and the functionality of smart pixel devices;
- To understand the operating principles and theory of optical waveguides
- Explain what an optical mode is
- Describe the applications and desired parameters of waveguides
- Describe the basic technologies available in optical waveguides
