Excitonic linewidth approaching the homogeneous limit in MoS2-based van der Waals heterostructures [PDF]
, 2017 The strong light-matter interaction and the valley selective optical selection rules make monolayer (ML) MoS[subscript 2] an exciting 2D material for fundamental physics and optoelectronics applications. But, so far, optical transition linewidths even at

1.5 μm lasers with sub 10 mHz linewidth [PDF]
Conference on Lasers and Electro-Optics, 2017 We report on two ultrastable lasers stabilized to single-crystal silicon Fabry-Pérot cavities at 124 K. The lasers show unprecedented thermal noise-limited frequency instabilities of 4×10−17 and linewidths below 10 mHz.

Laser linewidths: tutorial [PDF]
Journal of the Optical Society of America B, 2021 In this tutorial, the physical origins and mathematical analyses of laser linewidths are reviewed. The semi-classical model is based on an equation for the light-mode amplitude that includes random source terms, one term for each process that affects the amplitude (stimulated and spontaneous emission, stimulated absorption, and facet and material loss).

Ring-Resonator Based Widely-Tunable Narrow-Linewidth Si/InP Integrated Lasers
IEEE Journal of Selected Topics in Quantum Electronics, 2020 This paper presents recent results on widely-tunable narrow-linewidth semiconductor lasers using a ring-resonator based mirror as the extended cavity. Two generations of lasers on the heterogeneous Si/InP photonic platform are presented.

Hybrid integrated InP-Si3N4 diode laser with a 40-Hz intrinsic linewidth.
Optics Express, 2020 We demonstrate a hybrid integrated and widely tunable diode laser with an intrinsic linewidth as narrow as 40 Hz, achieved with a single roundtrip through a low-loss feedback circuit that extends the cavity length to 0.5 meter on a chip. Employing solely

Reduction of the spectral linewidth of semiconductor lasers with quantum wire effects—Spectral properties of GaAlAs double heterostructure lasers in high magnetic fields [PDF]
, 1986 The spectral linewidth of a GaAlAs double heterostructure laser placed in a high magnetic field is measured at 190 K. It is found that the power-dependent spectral linewidth is reduced by a factor of 0.6 in a magnetic field of 19 T.
