Quantum Well Lasers from the UV to the Infrared Chapter First Online: 31 March 2017
Part of the
Graduate Texts in Physics
book series (GTP) Abstract
Quantum well lasers are available in a large wavelength range, extending from the near UV to the near infrared. Basic materials are: GaN for UV and blue lasers; GaAs for red lasers; InP for near infrared lasers; GaN, GaAs or ZnSe for green lasers. We will discuss the design of different lasers.

GaN quantum well. The effective mass of (m \(^* \sim \) 0.2 m \(_0\)) of conduction electrons in GaN is about three times the effective mass of conduction electrons in GaAs. (a)
Compare the density of states of electrons in a GaN quantum well with the density of states of electrons in a GaAs quantum well.
Compare the condition of gain mediated by a GaN quantum well with the condition of gain mediated by a GaAs quantum.
