Four level semiconductor Laser

This is a schematic picture showing the principle of a semiconductor Laser. It also illustrates to some extent what this lecture course attempts to teach

	Semiconductor Lasers and light emitting devices are the paradigmatic devices of the non-Si semiconductor technology.
		However, while Silicon based microelectronics, and integrated circuit technology are usually covered comprehensively or even extensively in Materials Science and Engineering study courses, products and technologies based on other semiconductor materials are not.
		Non-Si semiconductors mostly are presented on a highly specialized level, if they are offered at all.
	What seems to be missing is an in-depth overview of all major aspects of all semiconductors. This lecture course attempts to do this (rather feebly at present).
		Everything relating to semiconductors except microelectronics will be covered in some detail - at least that is the idea.

Status

	This hyperscript was started as a collection of lecture notes for two lecture courses - Semiconductor I and II. However, Semiconductor IInever came into being so the Hyperscript remained incomplete, covering mostly just Semiconductor I topics. Some parts of Semiconductor II do exists, the switch over is somewhere between "Basic Optoelectronics" and "Lasers" (chapter 5 and 6, respectiveöy)..
		I'm not removing all those unfinished chapters and modules for two reasons: You can get an idea of what topics might be of interest for yout own research, and Taking the empty modulesout would ruin the internal link structurre of the Hyperscript, causing all kinds of unforeseen problems.

How to Start

	Use the Menu. This leaves four alternatives:
		Click on "Introduction" and start at the beginning.
		Click on the chapter of interest and take it from there.
		Click on "Project", click on "Matrix of Modules", and start with whatever looks interesting.
		Click on "Indexlist", see what catches your eye, click on it and see what you get.
	Go the direct way

Background Information

	This hyperscript used to be the script to a lecture course given by me. This lecture course has not been given for years and the Hyperecript now is a kind of stand-alone "book". It may still be used in ats by my successors. I have done some final editing but did not remove all allusions to lecture courses..
	This hyperscript contains many peculiarities in its formatting and style of writing. This was done with some objectives in mind. Find out about this here.
	There are more Hyperscripts available. If you are really curious about the Hyperscripts of "AMAT", you will find some information in the link.

Technical Information

	Which Browser should you use? This Hyperscript is optimized for the Windows Explorer but works also quite well with Mozilla.
		Other browsers might scramble equations. The link opens a "Check your Browser" page, which will show if your browser is OK.
	The "print friendly" and ".pdf" options only work for the "backbone" part of the Hyperscript (consult the "Matrix of Modules" for the meaning of "backbone").
	If you click on "Project" in the menu (or here), you will find some more information about the structure of this Hyperscript and the philosophy behind it.
		For example, if you like to read prefaces, you will find one there. It is the preface to "Electronic Materials", though
		Many other metafiles are also accessible from there.
	The remaining menu buttons (e.g. Indexlist etc.) provide automatically generated cross-linked lists which might be useful if you are looking for specific items.
