Noise, Dynamics and Squeezed Light in Quantum Dot Lasers

Semiconductor lasers have become vital in both scientific and engineering contexts, with significant advancements in their miniaturization since the 1960s. Key innovations include quantum dot (QD) lasers, which, alongside photonic integrated circuits (PICs), have transformed optoelectronics by enhancing scalability, energy efficiency, and cost-effectiveness through integration on a single chip.

Overview

A promising method for developing coherent laser sources involves growing III-V materials epitaxially on silicon. Noise reduction is crucial for ensuring laser quality, with methods like passive optical feedback and active electronic feedback being explored. However, feedback mechanisms can introduce nonlinear dynamics. The presentation will discuss QD lasers' robustness to optical reflections and sensitivity to optoelectronic feedback, as well as advancements in amplitude-squeezed light generation through low-noise pumping. These achievements pave the way for future high-performance classical and quantum light sources integrated on PICs.
