Module Description: This module provides a comprehensive overview of the physical principles and applications of optical sources, detectors and other components, and of optical systems. There is a significant emphasis given (a) to the semiconductor laser diode and (b) to spectroscopic optical systems.
Learning Outcomes
On successful completion of this module the learner will be able to:
LO1 Explain the physical principles and applications of optical devices and components, including sources, detectors and optical fibres;
LO2 Explain the physical principles and applications of the laser, especially semiconductor types;
LO3 Describe and explain the principles and applications of spectroscopic and related optical systems;
LO4 Demonstrate skills and safety in laboratory practice and optical measurements;
LO5 Solve numerical problems associated with optical devices, components and systems.
Pre-requisite learning
Module Recommendations

This is prior learning (or a practical skill) that is strongly recommended before enrolment in this module. You may enrol in this module if you have not acquired the recommended learning but you will have considerable difficulty in passing (i.e. achieving the learning outcomes of) the module. While the prior learning is expressed as named MTU module(s) it also allows for learning (in another module or modules) which is equivalent to the learning specified in the named module(s).

Incompatible Modules
These are modules which have learning outcomes that are too similar to the learning outcomes of this module. You may not earn additional credit for the same learning and therefore you may not enrol in this module if you have successfully completed any modules in the incompatible list.
Co-requisite Modules
No Co-requisite modules listed

This is prior learning (or a practical skill) that is mandatory before enrolment in this module is allowed. You may not enrol on this module if you have not acquired the learning specified in this section.

No requirements listed
