Summary: This article reports on the effects of Al2O3 passivation films deposited by atomic layer deposition (ALD) on the performance of high-speed oxide-confined single-mode (SM)-vertical cavity surface-emitting lasers (VCSELs). The ALD-deposited film alleviates carrier trapping caused by sidewall defects, resulting in significant improvements in static performance and a record-breaking modulation bandwidth of 29.1 GHz for the SM-VCSELs.

Summary: This paper presents a pulsed electrically pumped GaN-based vertical-cavity surface-emitting laser (VCSEL) at room temperature, with an n-GaN monolithic high-index contrast grating (MHCG) mirror. Experimental results show that lasing action begins at an injection current of 10.2 mA and the use of an n-GaN MHCG mirror significantly improves laser characteristics compared to previous work.

Summary: We investigate the modulation responses of injection-locked VCSELs using optical spin-polarization modulation technique and find that weak injection locking can maintain strong resonance response at high frequencies due to the linear birefringence of VCSELs. Our simulated results based on spin-flip rate equations match well with the experimental measurements, supporting the novel applications of spin-controlled VCSELs with injection locking.

Summary: Numerical study shows that VCSEL-SA exhibits pulse-like response below the threshold current when modulated by analog OOK current. In the excitable phase, the laser produces single spikes and a series of spikes with varying amplitudes corresponding to the current form. Complex dynamics, including bursting oscillations and chaotic dynamics, can be generated at low frequencies. After the excitable phase, the laser mimics the OOK current with underdamped oscillations during the OFF phase.

Summary: In this study, we investigate the dynamics of high-contrast grating vertical-cavity surface-emitting lasers (HCG-VCSELs) with a lateral optical feedback cavity. The lateral optical feedback cavity, achieved through reflection at the heterostructure interface, allows for tuning of the slow light effect and control over the dynamics of the HCG-VCSELs. Optical feedback enhances the -3 dB bandwidth, enlarges the eye openings, and reduces frequency chirp. The HCG-VCSEL with a lateral optical feedback cavity achieves a -3 dB bandwidth of 37.7 GHz and exhibits sufficient eye diagrams at 60 Gbps (non-return to zero format) and 50 GBaud (4-level pulse amplitude modulation format).

Summary: Edge-emitting lasers based on InGaAs/GaAs quantum heterostructures of transitional dimensionality, namely quantum well-dots, show a decrease in lasing-wavelength blue shift with increasing number of layers and optical confinement factor. However, in devices with single quantum well-dot layers or low optical confinement factor, lasing transitions directly from ground state to waveguide states, skipping excited states below <= 200µm, which is attributed to the abnormally low density of excited states in quantum well-dots.

Summary: Semiconductor lasers have rapidly developed in response to the growth of the global laser market. The use of semiconductor laser diodes is currently considered the most advanced option for achieving high-power solid-state and fiber lasers with optimal efficiency, energy consumption, and cost parameters. This work investigates an approach for optical mode engineering in planar waveguides known as Coupled Large Optical Cavity (CLOC), which allows for the selection of high-order modes through resonant optical coupling between waveguides. The state-of-art and application of the CLOC operation are reviewed and discussed, showing it to be a simple and cost-efficient solution for improving diode laser performance through numerical simulation and experiment.
