2. 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

3. 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 Technical Presentation versus Other Presentations

4. PowerPoint Presentation Guidelines Can’t Go WrongAvoid Background Plain White Distracting backgrounds Fonts Ariel Anything distracting Text Size Bigger than 18 point Smaller than 18 point (16 point) (14 point) (12 point) Colors Lots of contrast Little contrast between between text and text and background - background or distracting

6. PowerPoint Organization • Title Page • Outline – can be substituted for introduction slides • Body • Summary slide outlining conclusions

7. What to include on a PowerPoint Slide IncludeAvoid Graphs Long Derivations Diagrams/Pictures Computer Code Important Equations Lists of measurements Key measurements Conclusions

8. Two Pump Phase Matching Double Pump Configuration Single Pump Configuration Input signal (Pump1) Can be tuned throughout the whole bandwidth fp ( f 0 ) Limited tunability Converted signal Can be tuned throughout the whole bandwidth Converted signal Limited Tunability Input signal Pump Dummy signal Dummy Pump fin fc fs_d fin fp_d fc f0 (0) f0 (0) frequency  fp2 fp1 fp1 = fp2  f2 f1 • f1 =f2 fs1 = fs2  fs2 fs1 0: center wavelength fc = fin + fp_d - fs_d fc = 2*fp-fin • 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) Y.

10. 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

11. 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 Technical Content Mental state of most audience members: sleepy, lethargic, bored, distracted, defensive

12. 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

13. Acting Natural, Lots of Eye ContactExample

14. Integrating Microfluidics and Hollow Waveguides 4) End Coupling of Solid and Hollow Core Waveguides 3) Intersection of Solid and Hollow Core Waveguides 1) Hollow Core Waveguides 2) Bends and Intersections of Fluid Channels 5) Integration of Macroscopic Fluid Reservoirs

15. Don’t Read SlidesExample

16. 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 Fig. 4 Different carrier transportation routes within the device

17. Over/Under PrepareExample

18. Anti-Resonant Reflecting Optical Waveguides n3 n2 kx k d0 core,n1 kz n2 n3 Substrate 1) Hollow Core Waveguides • First proposed by Dugay et al. (1986) • High-index cladding: antiresonant Fabry-Perot cavity in transverse direction • Low-loss propagation in z-direction • Single mode • Additional layers reduce loss

19. Over/Under ExplainExample

20. SU-8 sacrificial core Waveguide width < 10 Top layer thickness • Rectangular core defined by photolithography • Core removal: H2SO4 + H2O2

21. Going Crazy with the Laser PointerExample

22. 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 . . .
