Semiconductor Optoelectronics -- Examination guidelines (Important)

Please read the following instructions/guidelines regarding the exam:

1. Answer all questions.

2. All Multiple Choice Questions (MCQs) have only one correct answer.

3. Read all the questions very carefully. Some questions may appear similar to the assignment questions, but they may not be the same.

4. It is important that you are well-versed with all the concepts covered in the course. Ask in the forums in case of any doubts.

5. Major formulae required to solve the numerical problems will be given in the question. All symbols in the formula will have their usual meanings, as used in the lectures.

6. Take care of the units in numericals to match with the units of the given options (MCQs) or the entered answer (fill in the blank questions).

7. In the fill in the blank type of questions, only the numerical values have to be entered, correct till two decimal places. The desired unit will be provided in the question, in brackets.

8. The values of the physical constant to be used are as follows:

Planck’s Constant h = 6.626*10-34 J.s
Charge of an electron e = 1.6*10-19 C

Mass of electron mo = 9.1*10-31 kg

kT at room temperature = 25 meV = 0.025 eV.

9. It is recommended that you use the simple approximation E (in eV)=1.24/λ(in μm), where applicable in the numericals. 

Important Note: Lectures 16 and 45 (“Fabrication of Heterostructure Devices” and “Photonic Integrated Circuits”) are not part of the syllabus, hence no questions will be asked from those two lectures.

Wish you all the best for the exam.
