Collapse Photon Detection with Superconducting Detectors from Millimeter-Wave to Gamma-Ray








Join the OSA Photonic Detection Technical Group and Dr. Jiansong Gao from the National Institute of Standards and Technology for a webinar on photon detection with superconducting detectors. Operating at a temperature less than 1 Kevlin above absolute zero, superconducting detectors provide ultimate sensitivity for photon detection and cover an ultra-wide wavelength range, from millimeter-wave, IR/visible/UV, to x-ray, and gamma ray. They are used in the most demanding applications such as the detection of cosmic-ray background (CMB) signal and single infrared photons.


The principle and recent progress of several important superconducting detector technologies will be presented by Dr. Gao in this hour-long webinar. Examples of their applications in quantum information processing and astrophysics will also be discussed during the webinar.


What You Will Learn in the Webinar:


In this webinar, the audience is expected to learn about the basics of superconducting detectors and their rich applications such as in quantum information processing and astrophysics.


Who Should Attend the Webinar:


PhD students, post-docs and young faculty members. This webinar would also be helpful for individuals working in the photonics industries.

Collapse The Debate: Lightfield vs. Holographic






The 3D displays of the future will not be like the 3D displays of today. We anticipate that we will be given displays like the holodeck from Star Trek. Displays that are realistic, unencumbered and interactive. But, while there is consensus on expectations, there is no consensus on technology.


Two technologies, in particular, seem to have the potential to deliver the realistic 3D of the future: holographic video and lightfield displays. Holography is both a physically and computationally intensive display method, which uses diffraction to recreate wavefronts of light that in some cases are optically indistinguishable from the wavefronts emanating from real objects. Lightfield displays, which include a large family of lenticular and coded aperture methods, are more concerned with matching the input of the human visual system than they are with exactly replicating wavefronts.  As a result, lightfield displays have been able to achieve more, faster in some cases than holography. But can they do as much as holographic displays? Does it matter? Can they do more? Will holography dominate in the 2030's when computational complexity is no longer an issue? Will something entirely new emerge?


Join the OSA Display Technology Technical Group and their guest champions, Dr. Levent Onural (Bilkent University) and Dr. Gordon Wetzstein (Standford University) as they engage in lighthearted debate on the relative merits of holographic video and lightfield displays.  Join the discussion yourself by submitting a comment to be read during the debate. Help us battle for the future this September 29th as part of what will undoubtedly be the most important debate of the year!

Send your questions for the debate to TGactivities@osa.org prior to the webinar.



What You Will Learn in the Webinar:

  • The comparison and contrast of lightfield and holographic displays.


Who Should Attend the Webinar:

  • Anyone interested in the future of 3D displays.

Collapse The Fascinating Optics of Metamaterials and Plasmonics






Metamaterials and plasmonics offer unprecedented opportunities to tailor and enhance the interaction of waves with materials. In this webinar hosted by the Nanophotonics Technical Group, Dr. Andrea Alu from the University of Texas at Austin will discuss his group's recent research activity in electromagnetics, nano-optics, and acoustics, showing how suitably tailored meta-atoms and suitable arrangements of them open exciting venues to manipulate and control waves in unprecedented ways.


Dr. Alu also will discuss recent theoretical and experimental results, including nanoclusters and metasurfaces to control wave propagation and radiation, large nonreciprocity without magnetism, large nonlinearities in tailored metamaterials, and parity-time symmetry in meta-atoms and metasurfaces. Physical insights into these exotic phenomena, new devices based on these concepts, and their impact on technology will be discussed during this one-hour webinar.


What You Will Learn in the Webinar:

  • Recent developments of plasmonic devices, metasurfaces, and acoustic/optical metamaterials.


Who Should Attend the Webinar:

  • Graduate students, postdocs and researchers interested in plasmonic and metamaterial devices.
  • Nanophotonic scientists and engineers working on the development of plasmonic devices and nanocircuits.

Collapse The Autostigmatic Microscope and Its Uses

Join the OSA Systems and Instrumentation Technical Group and Mr. Robert Parks for this webinar discussing the evolution of the classical autostigmatic microscope (ASM) into an all-purpose optical alignment tool whose use has been described in over 60 optical engineering papers that illustrate real-world systems applications. The evolution that led to the current instrument, the Point Source Microscope or PSM, is due to a convergence in technologies of solid state light sources, digital cameras, modest cost computers and software to operate these devices to create a small, lightweight and ergonomic optical test instrument with many functions.


After a brief introduction to the instrument and its optical layout, we describe its principle use, the measurement of radius of curvature of optical surfaces and test plates. Once its use for this function is well understood it will become obvious how to use an ASM for many alignment situations, particularly for optical systems that are spread out in space such as spectrometers, and systems that are folded into three-dimensional configurations. We also discuss a new way of thinking about alignment; not about where rays go through the system, but where optical surfaces and their centers of curvature are meant to go by design.


After discussing these paraxial methods of alignment, we talk about using aberrations for alignment of aspheric optics including off-axis parabolas and toroidal surfaces. We then turn to useful tips for planning alignment fixtures and using the ASM in conjunction with a coordinate measuring machine. We discuss the lens design of alignment set ups including the use of a zero index glass, and using this concept to find the surfaces and centers of curvature looking along the axis of a system. Finally we discuss the use of the ASM as an autocollimator and with computer generated holograms as a way of simulating centers of curvature in a three-dimensional volume.


What You Will Learn in the Webinar:

  • Attendees will learn the fundamentals of autostigmatic microscopes and how they are used to find the radius of curvature of optical surfaces. This background into fundamentals leads to discussing the use of the ASM in practical alignment situations.
  • Attendees will be presented with a variety of applications of the ASM to the alignment of optical systems, particularly applications that include aspheres and folded optics to give an appreciation for the capabilities of this technology.


Who Should Attend the Webinar:

  • Optical engineers and technicians who are responsible for assembling and aligning optical systems, particularly complex and high performance systems.
  • Opto-mechanical engineers who design the optical hardware into which optics are assembled so they appreciate that adding a few alignment datums in the hardware can speed assembly and improve the performance of the assembly.
  • All people involved with astronomical instruments as these engineers and scientists have been the quickest to appreciate what an ASM can do to aid in the assembly and alignment of these instruments.
