Description including Unit Aims

Passive Components

This course will describe in detail the key passive components in modern optical communication systems. It will cover both fibre-based and photonic integrated circuit components. Electromagnetic analysis will be used to gain an understanding of component operation

Optoelectronics and non-linear optics

This part of the module introduces the main techniques applicable to optoelectronic systems for the generation, detection, amplification and modulation of optical signals.

Elements:

Passive Components Dr M. J. Cryan

• Electromagnetic analysis of optical fibres, slab, ridge, deep-etched waveguides, co- and contra-directional couplers
• Filters, thin film devices, Fibre Bragg Gratings, planar waveguide devices
• More complex components which are used in Wavelength Division Multiplexing (WDM) systems, such as AWGs and Optical Add-Drop Multiplexers
• Future developments in these technologies will be reviewed and concepts such as Photonic Crystal-based devices will be introduced.

Active (optoelectronic) components Prof J.G. Rarity

• Describe the basic SNR properties of linear avalanche diodes and noise equivalent power
• Describe extension of avalanche diodes to Geiger mode photon counting
• Applications of photon counting detectors (lifetime measurement, quantum cryptography)
• CCD camera operation and performance
• CMOS camera operation and performance
• Free space optical communication systems
• Non-linear optics
• Three wave interactions, phase matching frequency doubling
• Four wave mixing, intensity dependent refractive index and the all optical switch, solitons self focussing
• Vertical cavity semiconductor lasers; principles of operation, advantages

Intended Learning Outcomes

Passive Components

Having completed this unit, the students will have a detailed understanding of the key passive building blocks in modern optical communications systems. They will be able to understand electromagnetic analysis of components such as optical fibres, planar waveguides and couplers. This will allow them to tackle design tasks on higher level components such as Array Waveguide Gratings (AWGs) which are constructed from a number of simpler building blocks.

Active (optoelectronic) components

Having completed the unit, students will be able to understand the operation of avalanche detectors, photon counting detectors, modern camera systems, three wave and four wave non-linear optics, free space optical communications and vertical cavity laser systems.
