Two-dimensional materials and van der Waals heterostructures as a novel platform for integrated optoelectronic devices

Abstract: The emerging field of two-dimensional (2d) materials provides an exciting opportunity to explore new technological paradigms in photonics and optoelectronics. The richness of optical and electronic properties of 2d materials and versatility of van der Waals heterostructures allow new approaches for designing novel optoelectronic devices across a wide range of electromagnetic spectrum. Despite being atomically thin, 2d materials strongly interact with light and pave a way to realization of various functionalities including energy efficient optical modulators, broadband photodetectors, light emitters, single photon sources, saturable absorbers, ultrafast lasers and more. In this talk, I will present my research on 2d materials based optoelectronic devices and hybrid 2d/3d systems, addressing graphene integration with silicon photonics and exploring van der Waals heterostructures for flexible photodetection and light emission applications. Key aspects related to device physics, material properties, fabrication process development and system performances will be discussed.

Bio: Dr. Ilya Goykhman is a Senior Research Associate at the Cambridge Graphene Centre (CGC) and a Lecturer at the Centre for Doctoral Training at the University of Cambridge. He leads Cambridge research activities on the topic of graphene optoelectronics in the European Graphene flagship program, with total funding of one billion Euro. He is a task-leader in optoelectronics work package in the Graphene flagship. Prior to joining CGC, he was graduated from the Hebrew University of Jerusalem. His major research interests are integrated 2d/3d devices and van der Waals heterostructures, with focus on optoelectronics, device physics, technology development of graphene and 2d materials, 2d/3d hybrid systems, flexible devices and advanced nano-fabrication techniques for applications in communication, light generation, quantum optics, sensing, memory and energy harvesting.

Transistor-Based Microwave Generators for Heating Applications

Abstract

In this study, mainly performed in 2005-6, we introduced the potential of replacing conventional magnetrons by solid-state devices for microwave heating, and presented an LDMOS-FET-based miniature microwave heater [Schwartz et al., IMPI 2006]. A more recent comparison among various types of transistors indicates that GaN-HEMT and LDMOS-FET transistors are the most promising technologies for producing microwave power at hundreds of Watts. In this study, a commercial LDMOS device designed as a 20-W power amplifier for communication base-stations has been used to produce heating power up to 200W in a feedback loop oscillator scheme. This pioneering device was studied in various schemes, including a cavity applicator for fluid heating; an active integrated antenna (AIA) in free space, and a delicate microwave drill (with the LDMOS-FET replacing the previously used magnetron). In addition, a novel method for monitoring varying load impedances in real-time environments was developed in order to be implemented in agile adaptive impedance-matching systems. The seminar will also present the state-of-art in solid-state application for microwave heating, including in future domestic ovens.

Interactive Information Theory

Abstract:
In a profoundly influential 1948 paper, Claude Shannon introduced information theory and used it to study one-way data transmission problems over different channels, both noisy and noiseless. That paper initiated the study of error correcting codes and data compression, two concepts that are especially relevant today with the rise of the internet and data-intensive applications.
In the last decades, interactive communication protocols are used and studied extensively, raising the fundamental question: To what extent can Shannon's results be generalized to the interactive setting, where parties engage in an interactive communication protocol? In this talk we will focus on the interactive analog of data compression in an attempt to answer the above question.
Bio:
I am a postdoc fellow at the Institute for Advanced Study (IAS), Princeton. I am very interested in applications of information theory to theoretical computer science, especially to communication complexity. Prior to joining the IAS, I completed a short postdoc at the Technion, received a Ph.d. and M.Sc. from the Weizmann Institute, and a B.A. from the Open University of Israel.

Space-Time Layout using a Neural Network

Abstract

Cameras are now ubiquitous in our lives. We carry them everywhere and record daily and casual activities without hesitation.

A given activity is often captured by multiple people from different viewpoints resulting in a sizable collection of photo footage even for a single event. We present a method that effectively organizes and summarizes this spatio-temporal content.

Given an unorganized collection of photos taken by a number of photographers, capturing some dynamic event at a number of time-steps roughly simultaneously, we would like to organize the collection into a Space-Time table. The organization is an embedding of the photos into an order-preserving view-point and time-steps clusters.

Our method relies on a self-organization map (SOM), which is a neural network that embeds the training data (the set of images) into a discrete domain. We introduce BiSOM, which is a variation of SOM that considers two features (space and time) rather than one, to organize the given photo collection in the table.

Time resolved computational imaging - from time-of-flight cameras to ultrasound tomography

Understanding the data formation models can allow us to extract meaningful scene information as well as correct for mistaken assumptions. In this talk I will look at two such cases, dealing with multi path interference and calibration issues with time-of-flight (ToF) cameras and sound speed recovery in ultrasound imaging.

Amplitude modulated continuous wave (AMCW) ToF range cameras operate by illuminating the scene with an amplitude modulated sinusoidal signal. Range is recovered by measuring the phase shift of the reflected signal, similar to a Michelson spectrograph. These types of cameras are sensitive to errors due to inter reflections in the scene (so called multi path) as well as errors in the illumination model. Using the non-linearity in the model along with frequency diversity, it is possible to deal with both these issues.

Similar to ToF, ultrasound imaging measures distance by measuring travel time. However, unlike the assumption of constant velocity of light when imaging in free space, the constant velocity assumption of sound fails when imaging inhomogeneous media such as the human body. Knowing background sound velocity is not only essential for being able to image by allowing focusing, research has shown that it also carries meaningful diagnostic information. Using synthetic aperture data, background scatterers along with scattering models allows us to correct for these errors and recover background sound velocity.

EE Seminar: Towards Synthesis in Real Life

Towards Synthesis in Real Life

Abstract
System synthesis refers to the task of automatically generating an executable system from a high level specification of its behavior. The basic idea is simple and appealing: instead of developing a system and then verifying that it adheres to its specification, we would like to have an automated procedure that, given a specification, constructs a system that is correct by construction. The first formulation of synthesis was given by Church back in the sixties, but the path to achieving it is strewn with difficulties. In this talk I will describe some of the challenges on the road to usable synthesis, a variety of current approaches for coping with them, and some success stories.

Short bio:
Dana Fisman is a research scientist at the University of Pennsylvania, the Associate Director of the NSF expedition ExCAPE about system synthesis, and a visiting fellow at Yale University. She did her PhD in Weizmann under the supervision of Amir Pnueli, and worked many years in the industry in IBM Haifa Research Labs, and in Synopsys Inc. Dana’s research interests are in the area of formal methods in system design. She is mostly known for her work on PSL, the IEEE standard for property specification language, on which she received numerous awards from IEEE, IBM and Synopsys.
