Question

Create your own minor optics research project. Find a question or procedure relevant to optics and write a short (1 paragraph or no more than about 1 page) synopsis of the optical phenomenon you find. The synopsis should include following: 1. Clear identification of optical parameters of the system 2. At LEAST ONE mathematical calculation relevant to the optical system 3. The included math should be explained 4. There should be at least some discussion of how the system is optimized if applicable. 5. Students may write up the same optical system but each report should be unique. Other considerations: 1. Grading will be approximately equivalent to 2 homework scores 2. Factors that will be considered in the final grade: Clarity and correctness Uniqueness-the more people that report on a common optical system the lower the bound will be on the score. Try to be unique if you can. Scores may also be increased if the project could be performed by the rest of the class using in house supplies or supplies that are easily obtainable. a. b. c. 3. This is meant to be a fun distraction, and some of the projects may be discussed in class (by Dr Note if the procedure requires information we have not yet learned in class, I will help. I don't want to give too many examples and steal anyone's ideas, but I will reiterate my former example Mitchell). Designing a Blu-ray disk player: .How is Blu-ray different than CD? Why can it hold more information on the same size disk? What optical elements are needed to read a Blu-ray? What are the parameters of the optics? Hypothetically, could we get better information density on the same size disk? . .

Explanation / Answer

1. Blue ray discs are different from normal discs in the basic design requirement. The blu ray CD uses 405 nm laser for read/wriote where as the normal CD uses 650 nm laser. Due to this, smaller phjysical modifications to the disc can be done on Blue ray adn hence greater data storage density.

2. It can hold more information on the same disc as due to the usage of smaller wavelength to read/write, more information can be saved per unit area , hence increased data storage density and hence more dfata can be stored on the disc of same size

3. A laser diode and Light dependent resistance ( or a diode) is needed to read and write ona b blu ray disc.
4. the laser diode has a wavelength of 405 nm.
5. Yes, better information density can be obtained by reducing the wavelenght of the light further, limited by diffraction limits and material interaction to wavelength limits.
