Introduction to semiconductor light sources and their biomedical applications

(03/10/2019) Introduction to semiconductor light sources and their biomedical applications The present chapter serves as a brief introduction to semiconductor light sources mainly laser diodes and light emitting diodes, and the basic physical properties of their semiconductor materials. The chapter also discusses the main reasons for semiconductor light sources being attractive for biomedical applications which range from patient diagnostics imaging to direct treatment such as using photodynamic therapy. It is expected that this specific application area will grow significantly in the future, and that it will be an increasingly important physical properties part of the semiconductor industry.
