Electrical Engineering Colloquium 

Speaker: Prof. Dana Ron

Title: On Imperfect but Very Fast Algorithms

Abstract 

Algorithms are usually considered efficient if they run in time that is polynomial in their input size. Assuming the algorithm reads its entire input, the best we can hope for is linear time. But what if the input is huge and we can’t afford even reading it entirely? Here is where sublinear-time algorithms come into play. Such algorithms do not read the entire input, but rather query/sample it. We allow them to give approximate answers, and fail with small probability. What we gain is efficiency.
 
In this talk, I will try to give a taste of sublinear algorithms.

Light refreshments will be served before the lecture

This colloquium is not counted toward seminar credit.

ההרצאה לא מזכה בקרדיט שמיעת סמינרים.

בשל שינויים של הרגע האחרון האירוע נדחה לסמסטר הבא, 

תודה לנרשמות! 

נציגות חברת אפל מגיעות אליכן במפגש און-ליין ייחודי 

מטרת המפגש הוא להכיר את העשיה של אפל בארץ, אך בעיקר לשמוע סיפורים אישיים של מהנדסות אצלנו שהתחילו בתור סטודנטיות,
עברו למשרה מלאה, התקדמו לתפקידים ניהוליים או עברו במגוון קבוצות ותפקידים באפל. 
 

המהנדסות ישתפו על חששות שהיו להם, אתגרים שהתמודדו איתם ועל השילוב של בית עבודה וחיים בכלל.

Abstract: Standard single-mode optical fibers and silicon-on-insulator photonic circuits are the most common and widely employed platforms of guided wave optics. Fibers have given us long-reach high-rate connectivity, and silicon photonics promises to do the same at the data center level. Both platforms are readily available for all to study and employ. The primary application of both fibers and silicon photonic circuits is the guiding of light in the linear regime. Neither is built for opto-mechanics. Yet, both systems can support interesting and useful interactions between optical and elastic waves, beyond what is commonly considered. nanostructures.

In this talk, I will present several examples of opto-mechanics in fibers and silicon photonics, providing a new take on how these everyday platforms may be used. Specific fiber-based results include the sensing of media outside cladding, where guided light cannot reach; non-reciprocal scattering and polarization switching; time-of-flight analysis of forward scatter; a new class of fiber lasers; and the optical stimulation of acoustic vortex beams. Silicon-based demonstrations include surface acoustic wave-photonic devices; the delay of signals on-chip by up to 175 ns; Microwave-photonic filters with a single, few MHz-wide passband; and electro-opto-mechanical oscillators.
