This course is designed to familiarize students with the fiber optics properties in a hands-on environment. The lab consists of 5 laboratory experiments and 1 lab project (PR). Students work in pairs and perform these experiments. Each group is required to submit a detailed report for each lab performed. Every next week is due date for each previous lab work. The lab report should be handed in and submitted electronically on mylearningspace before the lab starts.

For each lab you will take data, make plots, analyze it for its accuracy, and draw conclusion from your work. You must be prepared to discuss and demonstrate your experiment. When leaving the laboratory, ensure that you switch off and unplug all equipment and that your work area is left tidy and clean. Any changes will be posted on mylearningspace (MS). Please check the exact details each week.

Fiber optic areas covered in this lab are:
1. Measurement technique: power and wavelength measurementů.
2. FO physics characterization, parameters: Cut off frequency, NA, D(diameter) and MFD, Polarization and polarization dependence loss, Loss, absorption, dispersionů..
3. FO application: sensing, amplification, laser, couplerů.

Brief discription of each Lab work:
1 Optical power measurement.
The purpose of the exercise is to familiarize students with fibre optic measurements and measurement equipment.

2. Insertion loss.
The purpose of this experimentation is to practice taking measurements of insertion loss.

3. Propagation of light. Refractive index in optical fibres.
The purpose of this experiment is to learn propagation of light in optical fibres and measure refractive index of the fibre.

4. Fiber coupler.
The purpose for experimentation with fibre couplers is to understand the structure of a common four port fibre coupler as well as to be able to measure characteristics of these couplers.

5.Wavelength measurement and optical grating filter.
The purpose of this lab is to study Spectral Characteristics of traveling light in optical fibres and filtration of signal by grating based optical filter.

LAB REPORT for each experiment, if there is not lab evaluation scheme in a lab, should include the following :
(In this section describe the purpose, background (theory) and Method of the experiment)
I.Record of measurements: Original recording of data in the notebook in a form of a table with uncertainties. All data and notes should be entered into the lab notebook.
The results are a presentation of both observed and derived quantities.
- Calculate uncertainty of measured quantities
- Calculate combined uncertainty of derived quantities.
Derive results from least squares fitting of the observed data:
- Bring equation to the form y=ax+b
- Least squares fitting graph.
(a graph has a title, labeled axes, units, error bars and appropriate caption)
The discussion section is an opportunity to describe both the significance and limitation of your result (discussion of results and including sources of uncertainties).
This section is a concise summary of your experiment, main results, and their implications.

If there is a lab evaluation scheme in a lab then lab report can be in casual form - form of questions - answeres. Labs schedule:
Lab section L1: Mon, 8:30am - 10:20am, Room:N2094
Lab section L2: Mon, 10:30am - 12:20pm, Room:N2094
October 8 week is Thanksgiving Week

No Food or Drink is permitted in the lab. Enrolled students for course only allowed in lab. The laser will start about 10 second after it is switched on. DO NOT LOOK AT DOWN DIRECT LASER BEAM FOR ANY REASON. Block beam with supplied black safety screen to prevent stray beams round laboratory. Remove watches, rings and pendant jewelry when working with direct beam; they may reflect a beam into your eye. Do not unplug laser head from power supply even when switched off. Lasers operate are very high voltage and contain large capacitors which are dangerous even when disconnect from the main supply.
The lab should be kept tidy at all times. Please read and submit the Department Laboratory Safety Form

Attendance: It is expected that you will attend every class. Please be prompt. If you anticipate an absence, please let your lab instructor know immediately.

No one is admitted to the lab room 10 minutes after the lab begins.

If you miss a class with valid excuse you may make up the lab, it is YOUR responsibility to come in during open lab hours to make up the laboratory experiment. Every next week is due date for each previous lab work. Lab report should be handed in before the lab starts. At the end of the PC481 lab there will be lab test.

Lab Evaluation:
Each lab will be evaluated according following scheme unless there is an evaluation scheme in the lab manual:
Pre-lab question: 10%
Introduction: 10%
Result:data analysis: uncertainty calculation, graphing and least squire fitting:50%
Discussion/Conclusion: 30%
Total lab portion of the course: 25%
Always be on time!!
