2 Outline Examples of rogue events Their unusual statistics Difficulty in studying them Ultrafast phenomenon provides a good testbed and window Technical challenges and scientific tools needed Time-stretch technology Platform for creating real-time ultrafast t instruments t Extreme phenomenon observed in optics (Nature, December 2007) Taming and harvesting the extreme events Connection with socioeconomics Time-stretch imaging and its application to finding rare cancer cells (Nature, April 30, 2009) 2

3 Rogue Events, Outliers, Black Swans Singular, rare, but with massive impact A hallmark of complex systems Occur in social, financial and physical science Past behavior does not predict the future Risk analysis models fail October 2008 crash Do ow Jones Ind dustrial Avera age Stock Market Crashes Year 3

4 Other Examples of Extreme Events Rogue waves on the high seas Suwa-Maru sinks off the cost of Japan under moderate sea conditions (2008) Believed to be fiction until recently Natural disasters Evolution, survival of the fittestt DNA mutation Cancer: Single rogue cell triggers prostate cancer G.S. Bova et al. Nature Medicine, 2009 Rogue waves Communication Spontaneous noise Wave Height Fractal behavior, cantor set PMD errors in optical communication networks Time Size distribution of innovations 4

5 Highly Non-Gaussian Probability Distributions Highly Skewed power-law functions Characterized by a Heavy-tail Events much larger than the mean do occur Probability/Risk is much higher than predicted by Gaussian Classification using Mean and S.D. is inadequate Great impact in both finance and engineering Risk / Error Rate models fail Karl Gauss Extreme Value Distribution Probabili ity x exp Event Magnitude 5

7 It s Difficult to Model and Predict Extreme Events Understanding and modeling is hampered by Scarcity of the events Inability to do experiments Examples: oceanic rogue waves or financial markets Ultrafast phenomena provide an opportunity More data in a short time Laboratory experiments under controlled conditions Enough data to develop models and ability to test them 7

8 Extreme Value Events in Ultrafast Science Basic ingredients: noise and nonlinearities are present in: Electronic circuits: micro-seconds to nano-seconds Laser optics: pico-seconds to femto-seconds Many similarities il iti between optics and hydrodynamics d Soliton: wave packet that travels without spreading Turbulence occurs in both media Even gravitational field has an equivalent in optics Common mathematics in the form of NLSE Optical power => fluid density Optical Chirp => fluid velocity Soliton on a bed: group stays together Slowest runner Fastest runner 8

9 Can Ultrafast Phenomena Unveil the Mystery of Extreme Events? Opportunity: Controlled experiments in Table-top testbed Understand the underlying science Learn to engineer and harvest them Challenge: Detecting needle in haystack Requires: fine resolution, non-stop, high throughput Need to understand two classes of instruments: Equivalent time vs. real-time 9

10 Equivalent-time (sampling) Instruments Workhorse of ultrafast research Slows down the event using strobe light effect Works only for repetitive events Strobe light Doesn t really slow down the event, just under-samples it Cannot capture singular, transient events Picosolve TM : 600 Gsample/s equivalent time But only 20 Msample/s real-time! 10

11 Real-time Instruments Fine time resolution, no-stop sampling and long record lengths Holly grail of instrumentation technology What if we can stretch time? Truly slow down events Central theme behind a new class of instruments being developed at UCLA Persistence of Memory, Salvador Dali, 1931 Bahram Jalali & Fredric Coppinger, Data conversion via time manipulation, US Patent # 6,288,

12 Our Portfolio of Real-time Instruments Enabled by Time-stretch Time Stretch Digitizer Ali Motafakker Peter DeVore Brandon Buckley Shalabh Gupta Spectrometer Daniel Solli Jason Chou Camera Keisuke Goda Ata Mahjoubfar Ali Motafakker Kevin Tsia 12

13 Our Approach to Ultrafast Real-time Instrumentation Information to spectrum conversion Spectrum to time conversion Information + Step 1: Femtosecond pulse Group = Velocity Dispersion Map the high speed information onto the spectrum of a femtosecond pulse + = Step 2: Stretched pulse Spectrum is mapped into time Stretch the spectrum into time Digitize the slow waveform (and amplify at the same time) Real-time digitizer Time Stretch allows ultrafast events to be captured in real-time with conventional electronics 13

Arizona NSF CIAN ERC & DARPA electrical Fast Electrical signal Time optical Time Stretch electrical Stretched electrical signal Electronic Digitizer Dispersion Chirped Pulse Source Optical modulator PD 45-Gbps data captured using 1.5-GHz digitizer Chirped pulses Stretched pulse F. Coppinger, A. Bhushan, B. Jalali, Electronics Letters, 34 (4), Boosts the performance of electronics S. Gupta, A. Motafakker, B. Jalali, Appl. Phys. Lett UCLA Photonics Lab 14

15 Digitizing at 10 Trillion-times per Second in Real-time! 10 Tsample/s Transient Digitizer Sampling Interval = 100 fs 100 fs per conversion step Time stretch extends the performance of electronic digitizers to capture ultrafast events Creates the backend data acquisition needed to capture, store and analyze extreme value events J. Chou, O. Boyraz, D. Solli, and B. Jalali Appl. Phys. Lett. 91, (2007) 15

16 Time-stretch is not a Time Lens Time Lens Time Stretch Time-stretch is a Dispersive Analog Optical Link No need to disperse input signal No need to satisfy the lens equation B. Jalali, et al, Nature Photonics 3, 8-10 (2009) 16

17 Capturing Fast Optical Signals Requirement: fast and non-stop (real-time) Pump-probe Technique Pros: Ultra-fine temporal resolution Long delay Cornerstone of femto-chemistry Cons: Not a real-time technique Only works for repetitive events not applicable to random and rare events Spectrometer Prism CCD Camera Pros: detailed spectral information Cons: Too slow 17

18 A Brief History of Spectroscopy 1666: Newton uses lens and prism to disperse sunlight onto a screen 1812: Fraunhofer develops diffraction grating 1826: Kirchhoff and Bunsen use gratings to show that each element and compound has its own unique spectrum Newton Fraunhofer Kirchoff & Bunsen Fraunhofer demonstrates spectroscopy Speed ~ KHz Modern Optical Spectrum Analyzer 18

23 Optical Amplification in Silicon First demonstrated at UCLA in 2002 Pump Weak input Silicon Amplified Output 23

24 Extreme Value Statistics during optical amplification in Silicon Input distribution Output distribution Heavy tail Optical pulses follow the Pareto 80/20 law Photon Economics Unlikely connection between photonics and socioeconomics Both processes governed by the survival of the fittest Due to nonlinear response giving strong preference to the fittest 24 David Borlaug and Bahram Jalali, LEOS

29 Finding the Culprit The culprit is a particular type of noise at the input Intentionally introducing it seeds a rogue pulse Seed is very weak, 1/10,000 of the input Explains unpredictability of rare events 29 D.R. Solli, C. Ropers, B. Jalali, Phys. Rev. Lett.,
