To request a Distinguished Lecturer for an upcoming chapter event, review the list of Distinguished Lecturers’ various talks below and reach out to the lecturer directly via the contact information provided. Distinguished Lecturers are volunteers of the Society, not full-time staff. Meaning, lecturers determine their travel arrangements and time commitment around their individual, work-life balance schedules.
In order to secure a lecturer, make sure to contact the lecturers early and preferably months prior to your event. If a lecturer is available at the time of your event and accepts a talk invitation, the lecturer will travel to your chapter or give a virtual lecture at no cost to the chapter.
To address the needs of our Chapters, the Society's VP of Professional and Technical Development, with the support of the Board of Governors has proposed changes to the current program. The changes were ultimately approved by the IEEE and we are excited to announce that a revised Distinguished Lecturer program will begin with the next class in 2024.
Call for applications will be promoted starting May 2023, with a submission deadline of 31 August 2023. If you have any questions, please email PhotonicsSociety@ieee.org.

Semiconductor nanostructures with low dimensionality like quantum dots are one the best attractive solutions for achieving high performance photonic devices. When one or more spatial dimensions of the nanocrystal approach the de Broglie wavelength, nanoscale size effects create a spatial quantization of carriers along with various other phenomena based on quantum mechanics. Thanks to their compactness, great thermal stability and large reflection immunity, semiconductor quantum dot lasers are very promising candidates for low energy consumption and isolation free photonic integrated circuits. When directly grown on silicon, they even show a four-wave mixing efficiency much superior compared to the conventional quantum well devices. This remarkable result paves the way for achieving high-efficiency frequency comb generation from a photonic chip. Quantum dot lasers also exhibit a strong potential for applications in optical routing and optical atomic clock.Last but not least, a quantum dot single photon source is a building block in secure communications, and therefore can be applied to quantum information processing for applications such as quantum computers. This lecture will review the recent findings and prospects on nanostructure based light emitters made with quantum-dot technology. Many applications ranging from silicon-based integrated solutions to quantum information systems will be presented. In addition, the lecture will highlight the importance of nanotechnologies on industry and society especially for shaping the future information and communication society.

In this talk we plan to discuss a novel class of nanoscale devices that address unmet performance demands for applications in data communications. The performance of emerging generations of high-speed, integrated electronic circuits is increasingly dictated by interconnect density and latency as well as by power consumption. To alleviate these limitations, data communications using photons has been deployed, where photonic circuits and devices are integrated on platforms compatible with conventional electronic technologies. Within the dominant platform; namely Si, dielectric waveguides confine light via total internal reflection. This imposes bounds on minimizing device dimensions and density of integration. Those bounds arise due to the diffraction limit and the cross-coupling between neighboring waveguides. Nanoscale Plasmonic waveguides provide the unique ability to confine light within a few 10s of nanometers and allow for near perfect transmission through sharp bends as well as efficient light distribution between orthogonally intersecting junctions. With these structures as a building block, new levels of optoelectronic integration and performance metrics for athermal transceivers with achievable bandwidths of 100s Gbps and detection sensitivity better than -55 dBs, will be overviewed in this talk. In addition, opportunities for the role that 2D materials may pay in propelling these record performance metrics even further will be projected.

Sensing modalities and instrumentation for target detection and raging applications have received tremendous attention over the past decade. This has been driven in no small part by the unsatiable demand for cheaper, more compact and significantly improved Light Detection and Ranging (LiDAR), which is essential for autonomous navigation. The detection of objects in the presence of significant background noise is a problem of fundamental interest in sensing. In this talk I aim to demonstrate theoretically and experimentally how one can exploit non-classical light generated in monolithic semiconductor light sources in conjunction with non-local effects to enhance the performance of optical target detection and model LiDAR system.

Nanophotonics modelling for 21St century applications is becoming vital. The computational modeling provides a fundamental understanding of the relying physics behind the operation of photonic devices. However, computational modeling is still a challenge as some of the existing modeling techniques fail to capture the correct behavior of nano-photonic devices. In this regard, this talk will introduce an overview of the existing computational modeling tools for analyzing photonic devices, in general, and highlighting their salient features and shortcomings. It is well known that “plasmonics” plays a vital role now in localising the optical field beyond the diffraction limit and hence in integrated optics. Therefore, the talk will focus on plasmonics modeling issues and the failure of the classical electromagnetic solvers to accurately characterize the nano-plasmonic devices. Therefore, new accurate and stable beam propagation method will be introduced for analyzing plasmonics in the classical regime. The rigor of this approach is mainly because of relying on the finite elements method and the twice faster Blocked Schur algorithm which can exactly represent all the wide spectrum of radiation, evanescent, and surface modes produced by the strong discontinuity between metal and its surroundings. Moreover, in merging quantum plasmonic devices, it becomes essential to introduce “Quantum Corrected Model (QCM)” in order to accurately model these devices, and the basics of QCM will be also discussed.

Recent advancement in design and fabrication of multimode optical fibers, for example supporting stable propagation of orbital angular momentum modes or optical activity modes, have led to new advances and opportunities within nonlinear interactions. The nonlinear effects have applications that range from fiber lasers to optical communication using classical light, as well as quantum states. In the lecture, focus will be given to Raman scattering and four-wave mixing in multimode fibers supporting conventional linearly polarized modes and, more exotic modes as orbital angular momentum or optical activity modes. Examples of applications include amplification of structured light and generation and processing of quantum states.

Since the first demonstrations of the carbon-nanotube (CNT) mode-locked lasers and optical noise suppressors in 2003, over the years, it has bloomed into an exciting field of Nano-Carbon Photonics, using CNT, Graphene and other nano-carbon materials for various laser and photonics applications. In this lecture, we will look back to the historical development this research, exploring the ultrafast photonics properties of such materials, in particular for laser mode-locking. In the lecture we will talk about design aspects of mode-locked fiber lasers and some recent progress in this field. Some applications using these advanced laser pulsed sources will be introduced: e.g. a high-speed, high-sensitivity optical sampling oscilloscope using special long-wavelength femtosecond CNT lasers, for the optical communication industry, a non-contact, high-precision 3-D profile measurement system, using a high-repetition rate short-cavity CNT laser for the automobile industry, and bio-medical applications such as two-photon microscopy and coherent Raman microscopy.
