1) What are the material and diameter of the single mode fiber and multi-mode fiber, respectively?
2) Why is it much easier to couple light into a multimode fiber than a single-mode fiber? Then when should we use single-mode fibers instead of multi-mode fibers?
3) To maximize the coupling efficiency, should the NA of the lens be greater or smaller than that of the fiber? why?
6) What is fluorescence? What is two-photon absorption? What is two-photon excitation fluorescence microscopy?

Complete the following short answer questions: 1. Design an Ethernet network to connect a single client PC to a single server which will contain a wired connection to both digital storage media as well as an optical device. Both the client and the server will connect to their respective workgroup switches via UTP. Their workgroup switches are connected directly by a trunk link. The two switches are 1,700 meters apart. They need to communicate at 500 Mbps. Your design should...

1. Fill out the following table by indicating which general technique (light microscopy (LM) or electron microscopy (EM]) could be used to observe each structure or phenomenon. Put "no" in the box if the technique could not be used. If light microscopy can be used, name one technique (bright-field, phase-contrast, fluorescence, etc.) that you think would be effective. You will find some useful information in Appendix 1 of this manual and Chapter 18 of your textbook. Structure or phenomenon Could...
