What is Communication? The transmission of information/data from “sender” to “receiver”

What About Information? How much information is stored in servers by Youtube, Google, Amazon, Netflix, Hulu, Yahoo, Facebook, etc? Youtube: 100 hours of video uploaded every minute Facebook: 1.19 billion monthly active users, all uploading pictures of cats, and other important stuff. Google owns ~2% of world’s servers, probably over 1,000,000 servers As we develop faster methods to generate more data: higher quality cameras/video, portable sensors, etc., the amount of data generated will only grow exponentially In 2011, over 1.8 Zettabytes was created 1ZB=1,800,000,000,000,000,000,000 bytes 1ZB~18,000,000,000=18 billion hard-drives worth of data! All of this data requires faster/smaller processors, faster communication networks and…

Building a Communication System …the ability to move data from place to place!! Communication! Why Communication? Communication is important Science & Technology Business Arts & Literature Understand the world around us Programming Optics/Lasers Circuits Materials Science Cryptography Fun!

What makes a good communication system? Speed Reliability Security Capacity Reach Cost Ease of operation Portability Coverage Size

What goes into a communication system? Source Detector Medium Language/Code

Why nano? Typically we think of communication systems as taking data over miles and miles… We use light for this because optical fibers can carry light for long distances without loss And because light is fast!! But what about short distances? http://www.chipdesignmag.com/bursky/wp-content/uploads/2013/09/figure1-ibm-POWER8_die-high-res.jpg http://www.kurzweilai.net/images/future-3D-integated-chip.jpg

Transporting Information If we are transmitting information with light, we need waveguides Typically, we use waveguides made from glass: optical fibers Optical properties of a material can be summed up in n, the refractive index Glass Refraction Refraction Refraction Total Internal Reflection Reflection Reflection Reflection Reflection

Refraction How do we use refraction? Lenses Waveguides

Today’s Activity Make your own refractive elements! Use these to construct a path for light through an optical obstacle course! How to make the complete the course? That’s your problem! Process Design elements that can bend, steer, guide light. Optimize these components. How sharp of a bend can you make? What happens at internal reflection? What are advantages of lenses vs. waveguides? Develop a design for navigating the obstacle course Try to get the most light to the end of the course!

Optical Obstacle Course 10:30-11:00: Carve out lenses, prisms, waveguides and determine their properties 11:00-11:30: Take obstacle course layout and start adding your optical components 11:30-11:40 Build your optical system, see if you can get light to both port 1 and port 2! 11:40-11:50 Present your system to the group -discuss pros and cons -What are causes of loss? -room for improvement How do we go nano?
