A unified approach to the problems of semiconductor laser theory

A unified approach to the problems of semiconductor laser theory
A unified approach to the problems of semiconductor laser theory
This chapter is concerned with some of the fundamental problems of semi-conductor laser theory; more specifically, let us ask the questions:
(i) which problem remain to be solved?
(ii) of the remainder, which solutions are the most appropriate for given situations?
(iii) how much influence on laser development have the theoretical solutions had?

A conventional starting-point would be to discuss the historical progress of the laser from the early days of a low-power, high-threshold device requiring pulsed operation and/or a low-temperature environment, to the current situation of a wide variety of laser structures adapted for CW room-temperature operation, good mode control, ease of modulation, etc. A brief history of theoretical topics should include (chronologically) the reasons for high thresholds, the temperature dependence of threshold current, the role of dielectric waveguiding, the problem of heat dissipation, the gain-current relationship, transient behaviour (noise, resonance frequencies, 'spiking', modulation, time delays, Q-switching), electromagnetic mode control, carrier transport phenomena and many other topics.

Abstract

This chapter is concerned with some of the fundamental problems of semi-conductor laser theory; more specifically, let us ask the questions:
(i) which problem remain to be solved?
(ii) of the remainder, which solutions are the most appropriate for given situations?
(iii) how much influence on laser development have the theoretical solutions had?

A conventional starting-point would be to discuss the historical progress of the laser from the early days of a low-power, high-threshold device requiring pulsed operation and/or a low-temperature environment, to the current situation of a wide variety of laser structures adapted for CW room-temperature operation, good mode control, ease of modulation, etc. A brief history of theoretical topics should include (chronologically) the reasons for high thresholds, the temperature dependence of threshold current, the role of dielectric waveguiding, the problem of heat dissipation, the gain-current relationship, transient behaviour (noise, resonance frequencies, 'spiking', modulation, time delays, Q-switching), electromagnetic mode control, carrier transport phenomena and many other topics.
