The photonics research groups in the physics departments of Heriot-Watt and St. Andrews Universities are internationally renowned, and have many links with industrial and university groups around the world. Major activities are based around optoelectronics, laser development, semiconductor physics, materials technology, ultra-fast phenomena, modern optics, and instrumentation. This expertise is brought to the teaching of our one-year taught MSc course.
Previously called Optoelectronic and Laser Devices, this MSc course has been updated and enhanced, recognising the explosive growth of the UK and global photonics industry, fostered by the world-wide expansion in the exploitation of optical in telecommunications. Students receive postgraduate training in modern optics and semiconductor physics tailored to the needs of the optoelectronics industries. Graduates gain an understanding of the fundamental properties of optoelectronic materials and optical fibres, and experience of the technology and operation of a wide range of laser semiconductor devices appropriate to the telecommunications, information technology, sensing, and manufacturing industries.
Students spend one semester at each university, and then undertake a three-month research project, normally in a UK company. Companies participating in recent years include Bookham Technologies, BAE Systems, Edinburgh Sensors, Cambridge Display Technology, Defence Science and Technology Laboratory, Indigo Photonics, Intense Photonics, Kamelian, Nortel, Renishaw, Rutherford Appleton Laboratory, Thales, Sharp and QinetiQ.

Teaching comprises lecture modules, tutorials, and laboratory work. Students move their accommodation from St Andrews to Heriot-Watt university part way through the teaching session (near the start of February).
Students are also expected to attend relevant research seminars and departmental colloquia which are held regularly, and which reflect the research interests of the physics departments in St Andrews and Heriot-Watt. Seminars and Colloquia are given by departmental research staff, specialists from other universities and specialists from industry.
Work for lecture modules is assessed through examinations whereas the laboratory work is assessed in a continuous manner. Lecture courses are examined at the end of each teaching block.
The project placement which occupies 12 weeks within June, July and August is assessed in September after the submission of a dissertation and an oral exam.

Aerospace applications of photonics. Engineering management. Pulsed laser material processing. Future optoelectronics research.
Innovation & Team Work ~ 20 hours.
The course will involve lectures, "practical" sessions, and team-work in which a product is taken from inception to sales and servicing. Lecture topics are: Invention in a commercial setting, driving forces, challenging linear thought, the inventive step, engineering & rethinking, IPR & patents, following through with the product.
Aspects not covered by the above sessions (patents, IPR, business formation, venture capital, the planning process, negotiation, the leadership process)
Literature surveys & Report writing
All full-time students carry out one minor literature survey, from a selection of topics. In addition they carry out a major survey and write a report on the topic area of the summer research project. This has the added benefit of establishing the projects in good time, and means that the student is well prepared in the topic when he/she starts the project in early June.
Poster & Oral presentations
At the time of the Industrial Advisory Committee meeting (spring), all students prepare and present posters covering one of their laboratory experiments. Both the scientific content and the presentation are judged. Students are also assited to give talks on a topic of interest.
6. Laboratory and Project Work
The well-equipped photonics teaching laboratories at the two sites give students a range of useful practical experience. Students spend three afternoons a week in these labs.
IMPORTANT NOTE: Per 6 April 2015 only the English language tests from IELTS and Trinity College London are accepted for Tier 4 Visa applications to the United Kingdom. Other tests (including TOEFL, TOEIC, Pearson, City & Guilds) are no longer accepted for Tier 4 visa applications to the United Kingdom. The university might still accept these tests to admit you to the university, but if you require a Tier 4 visa to enter the UK and begin your degree programme, these tests will not be sufficient to obtain your Visa. Since the Trinity College London language tests must be taken in one of their exam centres in the UK, IELTS is now the only language test accepted for Tier 4 visas to the UK that can be taken worldwide.
Applicants from the UK should have at least a 2ii degree in physics or electrical engineering or related, with the best qualified students likely to have priority. Applicants from other countries should possess similar qualifications, and will also need to show evidence of competence in the English language. Applicants should be aware that this is a physics-based degree, so a good working knowledge of physical and mathematical concepts is needed.
For those whose first language is not English, we normally require one of:- an IELTS average score of at least 6.0 with a minimum score of 6.0 for both reading and writing; TOEFL paper-based score of at least 580, or computer based at least 240; Cambridge Certificate of Proficiency in English of at least grade C.
No work experience is required.
Fortunately enough I was able to find StudyPortals. Right from the start of the application to getting the confirmation of admission I was using StudyPortals.
