Quantum Mechanics for Scientists and Engineers

On-Line Quantum Mechanics MOOC (Massive Open On-line Course)

This course will start on September 30, 2014

Registration link: http://quantum.class.stanford.edu

Free, open enrollment

This course aims to teach quantum mechanics to anyone with a reasonable college-level understanding of physical science or engineering. Quantum mechanics was once mostly of interest to physicists, chemists and other basic scientists. Now the concepts and techniques of quantum mechanics are essential in many areas of engineering and science such as materials science, nanotechnology, electronic devices, and photonics. This course is a substantial introduction to quantum mechanics and how to use it. It is specifically designed to be accessible not only to physicists but also to students and technical professionals over a wide range of science and engineering backgrounds.

Recent Hot Topics:

How to design any linear optical device ... and how to avoid it

(See also a recent open Lecture on this topic)

Self-aligned coupler

We can think of many different optical components we might like to make but that we have not known how to design. A good example is a mode-splitter that could separate multiple overlapping beams without loss. Up till now, we have had to use techiques such as "blind" design by optimization or exhaustive search, and it has not generally been obvious whether the device we wanted was even possible physically. Now we show how to design any linear optical component; the method always works and actually requires no calculations at all.

Are optical transistors the next logical step?A transistor that operates with photons rather than electrons is often heralded as the next step in information processing, but optical technology must first prove itself to be a viable solution in many different respects. This article is a Commentary written for Nature Photonics, January 2010.

Quantum Mechanics Book

Quantum bookThis introductory quantum mechanics text is now being published by Cambridge University Press. It is intended both for physicists and for those from other scientific and engineering disciplines, including electrical and mechanical engineering, materials science, and nanotechnology. The level of presentation is suitable for junior undergraduates through graduate students to technical professionals. Requirements for both physics and math are minimized, and the necessary background in these areas is summarized in appendices. Core topics are covered, the quantum mechanics for key areas of application in electronic and optical devices is explained, and advanced techniques and areas, such as the quantum mechanics of light and quantum information, are introduced.This is the textbook for both the EE222 and EE223 (Applied Quantum Mechanics I & II) classes at Stanford.

Other Hot Topics:

Device requirements for optical interconnects to chipsThis invited paper for the July 2009 Special Issue on Silicon Photonics in the Proceedings of the IEEE discusses the targets and requirements for optoelectronics and optical devices if they are to meet the needs of future interconnects to chips. Energy per bit is particularly important, with 10 fJ/bit being a key device benchmark. The various approaches to optical and optoelectronic devices and technology are summarized and compared.

Fundamental limit to optical components We have derived an upper bound to the possible performance of linear optical components of given sizes and maximum dielectric constants. (Most downloaded article from all OSA journals other than Optics Express, October 2007)See also the Physical Review Letter on a general limit to one-dimensional slow light structures and a brief summary in Optics and Photonics News "Optics in 2007"

Nanometallic-enhanced photodetectorsHertz dipole enhanced photodetectorWe have demonstrated that nanometallic structures can enhance photodetection, promising very low capacitance optoelectronic devices compatible in size with CMOS transistors. A nanoscale C-shaped aperture in a metal can enhance the photocurrent in the semiconductor beneath it, and recently an optical analog of a Hertz dipole antenna concentrates light to a ~ 100 nm sized germanium detector element on a silicon substrate.

Quantum-confined Stark effect in germanium quantum wellsA new modulation mechanism for silicon-compatible optics, promising low energy devices for optical interconnects. See the Nature letter, a longer JSTQE paper on the original observations, the first modulator, a low-voltage C-band modulator, and a recent JSTQE paper on the detailed physics.
