Metasurfaces are a new optical element that allows complete control over all aspects of light (phase, wavelength, intensity, and polarization) with a single, planar semiconductor layer. Comprised of subwavelength nanostructures, a single metasurface can carry out optical functions typically requiring four or more conventional refractive and/or diffractive optics, enabling new forms of sensing at a form factor and price point compatible with mass markets. This presentation will discuss metasurfaces from fundamental concepts to commercialization at Metalenz. We will discuss how metasurfaces are mass produced in the same semiconductor foundries making image sensors and electronics, moving large-scale production of optics into the foundry for the first time. We will also explore how the multi-function performance capabilities of a single metasurface in combination with the large-scale manufacturing capabilities of semiconductor foundries allow Metalenz to proliferate forms of sensing that have previously only been accessible in scientific or industrial laboratories.

Looking into the Early Universe with the James Webb Space Telescope
Launched Christmas Day 2021, the James Webb Space Telescope (JWST) will be the flagship astronomical facility of the coming decade. As a large-aperture infrared-optimized telescope, it will provide a stunning new view of the Universe and permit study of astrophysical questions that we have simply not had the capacity to address before. I will present an overview of the telescope and describe how it will transform the study of the early evolution of galaxies.
We will start the Zoom session 15 min prior to the presentation for debugging connection issues for online participants

Optical Communications for Human Space Exploration
MIT Lincoln Laboratory is currently developing optical communications technologies to support a variety of future NASA missions, including human space exploration efforts. The Artemis II mission, which will return humans to the Moon for the first time since the Apollo missions, will include an optical communication payload for the Orion Artemis II Optical Communications (O2O) demonstration. The recently launched Laser Communications Relay Demonstration (LCRD) provides an optical relay that will communicate between ground terminals and the soon to be launched Integrated LCRD Low-Earth Orbit User Modem and Amplifier Terminal (ILLUMA-T) aboard the International Space Station. This talk describes the development and status of these systems.

A look back at 10 years of student-led development of first-order search and evaluation tools for the design of complex zoom lenses
When presented with a new design request it is not unusual for an optical designer to start from an existing design that was chosen based on its underlying design form and then scaled to meet system requirements (e.g. focal length). However, the design of a new zoom lens is complex and typically requires a designer to “start from scratch”. As a result, considerable emphasis must be placed on the first-order configuration of the starting point design especially since constraints on packaging parameters (e.g. length, diameter, working distance) can change the first-order solution space significantly. This talk will take a historical look at the student-led development of Excel, Matlab, and Python zoom lens tools for automating the Monte Carlo first-order search, visualizing the zoom motion, and quickly evaluating the performance of a complex zoom lens.

Continuing the Search for Equity: Advancing the Need for More Representation of Black Scientists in Optics and Photonics
The events of 2020 have forced us all to confront the dark truths of racial injustice and police brutality that so many black people have endured for decades. The scientific community especially had its own awakening to the bias, indifference, and discrimination that black scientists have seen and experienced, including the fact that as a whole, the many contributions that black scientists have given to science have not been embraced nor celebrated by their colleagues mainly because of their skin color. In this presentation, I share my story on how I was able to earn the Ph.D. in optics through my matriculation of entirely all historically black colleges and universities, how the black scientific community responded to the cry for racial equality, and why it is so important to advocate on their behalf for racial equity in the sciences.
