"FM Radio at 560 THz Enables Single-Molecule Detection and Spectroscopy, Paving the Way to the Nobel Prize"
by Professor W. E. Moerner, WN6I, Nobel Laureate
Prof. Moerner will talk about science in his youth, concentrate on the original experiment as a signal detection problem similar to FM in ham radio, and briefly mention some of the current work.
W.E. Moerner's early years as a ham in high school eventually led to the study of electrical engineering, physics, and mathematics in college and optical studies of vibrations of molecules in graduate school. All of these experiences built upon themselves throughout his career, eventually leading to the optical detection of a single molecule in a solid in 1989 at IBM Research. This was achieved with laser FM spectroscopy, which involves frequency modulating a visible light beam at low modulation index to detect narrow spectral features with quantum-limited sensitivity. Effectively, the single molecule acts as a demodulator of the FM signal, converting the FM to AM, much like good old FM radio, but at 560 THz. This was the beginning of single-molecule optical studies which are having a broad impact on imaging in chemistry, physics, and biology today.

The PAARA Board meets on the 3rd Wednesday of every month at 7:00 pm (19:00 J) at Round Table Pizza, located at 1225 El Camino Real, Menlo Park, CA 94025, just a few blocks north of Su Hong. We conduct most of our club business here in order to allow more time for guest speakers and socializing at regular club meetings. Any PAARA member is welcome to attend.
A few meetings throughout the year have pre-defined agenda items. These include:
September Board Meeting
The Nominating Committee is appointed by the President to decide on a slate of candidates to be recommended to the membership.
October General Meeting
The Nominating Committee presents its nominations to the membership at the regular club meeting. Nominations from club members opens at the beginning of the meeting, and closes at the end of the meeting.
December General Meeting
Elections are held at the December annual meeting.
