Oded Yaakobi 
Oded Yaakobi is a theoretical physicist with broad academic and applied experience, who is interested to focus his research efforts in directions that could lead to practical applications. He has graduated his B.Sc. in Physics and Mathematics at The Hebrew University of Jerusalem in the excellence program Talpiot (1999). [Talpiot is an elite Israel Defense Forces training program for young people who have demonstrated outstanding academic ability in physics and mathematics]. Oded completed his M.Sc. at TelAviv University (Magna Cum Laude, 100/100 in the final exam) under the supervision of Prof. Zilman and Prof. Miloh while serving as a Research Officer in the Navy (2005). His M.Sc. thesis was devoted to studying the feasibility of a novel method for detection of a moving body in electrically conductive seawater due to the magnetic field induced by its wake. In his Ph.D. at The Hebrew University of Jerusalem, Oded studied theoretical aspects of resonant wave interactions under the supervision of Prof. Lazar Friedland (2011). During his Ph.D., Oded worked as a Researcher in the group of Dr. Henis at Soreq Research Center, and collaborated with the groups of Prof. Wurtele and Prof. Siddiqi from UC Berkeley. In 2011, Oded joined the Nonlinear Photonics group at INRSEMT as a postdoctoral fellow. Oded is the first author of 10 peerreviewed journal papers and 3 peerreviewed conference proceedings. His scientific achievements were acknowledged by national and international organizations (e.g. APS, ICPSA) by means of prizes, scholarships and grants. In 2011, he was awarded the prestigious Barenholtz Prize for Creativity and Originality in Applied Research for his work on autoresonant fourwave mixing in optical fibers. In 2012, he was ranked in The First Place in the FQRNT Excellence Scholarship Program Competition for Foreign Scientists (Quebec, Canada) with a research proposal that is related to this project. He is a reviewer for 9 journals e.g. for: The American Physical Society (APS)  Physical Review B and Physical Review E, The Optical Society of America (OSA)  Optics Letters, Optics Express and Journal of The Optical Society of America B, etc. Oded enjoys very much the process of integrating analytical methods with numerical techniques. Usually, the first step of his work on a new project is programming and solving the relevant set of equations numerically using MATLAB. This stage assists him to obtain some insight on the problem. Based on this preliminary understanding, he formulates the analytic theory and validates it by comparison with numerical results. In his joint work with advisers and colleagues he played a major role in constructing the analytical theories. In addition, he has developed from scratch almost all the codes that were used for solving the mathematical models either symbolically or numerically.

Research Project Autoresonance Effects in Nonuniform Second Order Nonlinear Materials: ThreeWave Mixing (TWM) processes appear in many fields of physics e.g. nonlinear optics, plasma physics, acoustics and hydrodynamics. In TWM, the sum of the frequencies of two waves is equal to the frequency of the third wave ( w_{1} + w_{2 }= w_{3 }). Recently, a general theory of autoresonant threewave mixing in a nonuniform medium has been derived analytically and demonstrated numerically [1]. It has been shown that due to the medium nonuniformity, a stable phaselocked evolution is automatically established. For a weak nonuniformity, the conversion efficiency between the interacting waves can reach almost 100% of the pump energy (see Fig. 1). We have shown that due to mechanisms different from those previously reported, it is possible to establish an autoresonant state in wavemixing processes, resulting in pumpdepletion, also in the absence of selfphase and crossphase modulation effects. Our work generalizes previous studies about twowave mixing processes in spatiallyvarying media [2,3] and TWM in the undepleted pump regime (which is effectively a twowave mixing process) [4].
One of the potential applications of our theory is the design of highlyefficient Optical Parametric Amplifiers (OPAs) allowing complete pump depletion. This kind of OPAs is expected to have a very large amplification bandwidth with a flat amplification spectral profile, similarly to what have been suggested and demonstrated in the case of fourwave mixing in tapered optical fibers (see Fig. 2) [5].
The robustness of the autoresonance effect makes it an attractive concept that has already been implemented in many fields of physics and engineering and has potential to many industrial applications. A variety of exciting new autoresonant applications in the field of nonlinear optics is currently being investigated by us. For more information about past projects about autoresonance see Dr. Oded Yaakobi website.
