Quantum Fluctuations and Amplitude Squeezing in Quantum-Confined Lasers

This chapter is devoted to the investigation of quantum fluctuations and amplitude squeezing in quantum-confined lasers. In semiconductor lasers, the presence of quantum fluctuations has been a longstanding concern. The presence of intrinsic constraints on electromagnetic field measurements can be related to the principles of quantum mechanics. The emergence of quantum technologies has rekindled interest in generating quantum states of light using semiconductor lasers. A significant factor that distinguishes semiconductor lasers from other laser types is their pumping mechanism. Specifically, semiconductor lasers are pumped by injection current delivered through an electrical circuit.
