Presentation on Presentation IMMERSE 2015 4 -29 -15
Outline • Technical presentations versus other • Using Power. Point 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 – Power. Point Church Presentation – Usually do a fraction of talking (5% R. S. ; 10% priesthood) – Include stories, feelings, personal experiences – More personable – You ask the questions
Power. Point Presentation Guidelines Background Can’t Go Wrong Plain White Avoid 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 between text and background Little contrast between text and background or distracting

Point Presentation Guidelines Can’t Go Wrong Avoid Background Plain White Distracting backgrounds Fonts Ariel Anything distracting Text Size Bigger than 18 point Smaller than 18 point (14 point) (12 point) Colors Lots of contrast between text and Little contrast between text and background - background or distracting
Power. Point Organization • Title Page • Outline – can be substituted for introduction slides • Body • Summary slide outlining conclusions
What to include on a Power. Point Slide Include Graphs Diagrams/Pictures Important Equations Key measurements Conclusions Avoid Long Derivations Computer Code Lists of measurements
Two Pump Phase Matching Double Pump Configuration Single Pump Configuration Input signal fp ( f 0 ) (Pump 1) Limited tunability Converted signal Can be tuned throughout Input the whole bandwidth Limited Tunability Pump signal fin Dummy signal fc f 0 ( 0) f 1 f 2 frequency fs_d D f 1 = f 2 0: center wavelength fc = 2*fp-fin Converted signal Can be tuned throughout the whole bandwidth Dummy Pump fin fp 1 fs 1 f 0 ( 0) fp_d fc fp 2 fs 2 fp 1 = fp 2 fs 1 = fs 2 fc = fin + fp_d - fs_d • 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.

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 Mental state of most audience members: sleepy, lethargic, bored, distracted, defensive 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
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 Contact Example
Integrating Microfluidics and Hollow Waveguides 4) End Coupling of Solid and Hollow Core Waveguides 5) Integration of Macroscopic Fluid Reservoirs 1) Hollow Core Waveguides 3) Intersection of Solid and Hollow Core Waveguides 2) Bends and Intersections of Fluid Channels
Don’t Read Slides Example
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
Over/Under Prepare Example
Anti-Resonant Reflecting Optical Waveguides 1) Hollow Core Waveguides n 3 n 2 d 0 kx k core, n 1 kz n 2 n 3 Substrate • 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
Over/Under Explain Example
SU-8 sacrificial core • Rectangular core defined by photolithography • Core removal: H 2 SO 4 + H 2 O 2 Waveguide width < 10 Top layer thickness
Going Crazy with the Laser Pointer Example
Conclusions • Being well spoken in technical presentations extremely important • How strangers see you • Practice, practice. . . • Watch other people and decide what you like, what you don’t • Let’s learn from each other. . .
