IMMERSE 20154-29-15
Outline• Technical presentations versus other• Using PowerPoint Slides
• Backgrounds, colors, fonts, sizes• Organization• Too much/too little information
• Content• Enough background information for your audience• Avoid equations and gory details• Emphasize big picture and conclusions
• Presenting• Try to be natural – lots of eye contact• Don’t read slides• Don’t over/under prepare• Don’t over/under explain• Don’t go crazy with the laser pointer
Technical Presentation versus Other Presentations
Technical Presentation– You do all the
talking until someone asks a question
– Delivering scientific results
– Can have “personality” but should maintain a degree of professionalism
– PowerPoint
Church Presentation– Usually do a
fraction of talking (5% R.S.; 10% priesthood)
– Include stories, feelings, personal experiences
– More personable– You ask the
questions

• Middle of the two pumps (input signal and dummy pump) needs to be ~ 0 We tune dummy pump wavelength to get input wavelength tunability• Middle of the dummy signal and the converted signal needs to be close to 0 We tune dummy signal wavelength to get input wavelength tunability• tunability is limited by EDFA (~ 25 nm)

Videos and Animation
• Can be extremely effective• Embed and make sure it’s bulletproof• Don’t leave video looping
Technical Content
Background– Adjust to your audience– What do you need to know to understand
significance of what I’m talking about– Why should you care– Why what I’m doing is so great
Background slides could range from 1 to most of the talk depending on your audience
Technical Content
Things people like • Big pictures• Summary• Results• New Stuff• Simple
explanations
Things people don’t like
• Thinking too hard• Gory details• Repetition• Endless equations• Meaningless
information• Endless talking
Mental state of most audience members: sleepy, lethargic, bored, distracted, defensive
The Act of Presenting
• Try to be natural – lots of eye contact• Don’t read slides• Don’t over/under prepare• Don’t over/under explain• Don’t go crazy with the laser pointer
Acting Natural, Lots of Eye ContactExample
4) End Coupling of Solid and Hollow Core Waveguides
3) Intersection of Solid and Hollow Core Waveguides
5) Integration of Macroscopic Fluid Reservoirs
2) Bends and Intersections of Fluid Channels
1) Hollow Core Waveguides
Integrating Microfluidics and Hollow Waveguides
Don’t Read SlidesExample
SIM – Key to the Operation
Electrons created during ionization are collected at N+ region.
Holes created during ionization are directed towards the P+ substrate instead of back towards the current source
→ avoid carrier recombination and gain suppression

• Low-loss propagation in z-direction• Single mode• Additional layers reduce loss

Conclusions
• Being well spoken in technical presentations extremely important
• How strangers see you• Practice, practice, practice . . .• Watch other people and decide what
you like, what you don’t• Let’s learn from each other . . .
