We propose a silicon based quantum well nanolaser structure based on surface plasmon polariton (SPP). The InGaAs/InP multi-quantum well in this structure can be obtained by direct epitaxy growth in nanoscale V-grooved trenches on silicon substrate by the high aspect ratio trapping method; and through the deposition of the metal layer and dielectric layer to excite the property of the SPP. The finite element method is used to simulate the electric field distribution of the laser mode and the variation of the mode characteristics, waveguide characteristics and threshold characteristic of the optical communication band with the geometric parameters. The results show that this structure has a better ability to limit the optical field and can realize deep sub-wavelength constraint of the output optical field at a lower threshold level, which is an expected idea of the high-performance and miniaturized silicon-based nanolaser.

Due to its unique optical and electrical properties, gallium nitride (GaN) exhibits great promise for nanolaser cavities. These characteristics include high electron mobility, wide bandgap energy, and a high refractive index. Moreover, GaN exhibits remarkable thermal stability, making it appropriate for high-power laser applications. The choice of active medium material can significantly impact the laser's performance, including its wavelength, output power, and efficiency. This work designed and numerically demonstrated a GaN -WG built-in SiO_2 substrate with an input and output Si-waveguide nanolaser. These nanolasers lase multi-output wavelengths in both directions (forward and backward) at 1680 and 1750 nm, respectively. The pump power is 800 nm. The GaN- waveguide material, when used in nanolaser cavity design, gives many different advantages like concentration of the Gaussian envelope and improved polarization depending on rate (PDR). Increasing lasing efficiency by 76.6 % in the forward direction and 96.7% in the backward direction. Get a low lasing threshold of approximately 200 μW in the forward direction and 180 μW backward direction. Finally, improved the output laser power in both directions (460 μW and 600 μW) in the forward and backward directions, respectively.

“…To further improve the structural properties of hybrid SPPs waveguide, emerging 2D materials such as graphene, [18][19][20] transition metal dichalcogenides (TMDs), and perovskite have been proven to be excellent auxiliary gain materials for exploring novel plasmonic nanolaser. [21][22][23] For example, Li et al demonstrated that monolayer MoTe 2 can support the laser operation in a silicon-based nanolaser at a low temperature.…”

This work theoretically proposes a novel surface plasmon polaritons nanolaser enhanced by 2D black phosphorus (BP) nanosheets, which can greatly enhance the local electric field and reduce the normalized mode area. The plasmonic nanolaser is created by integrating few-layered BP nanosheets into a hybrid waveguide structure consisting of a cadmium sulfide (CdS) semiconductor nanowire, a low-index dielectric MgF 2 buffer film, and a silver substrate. Both the electric field distribution and mode parameters originating from the proposed hybrid structure are systematically studied. The simulation results show that, under the optimal conditions with r = 95 nm, h gap = 2 nm, and d = 1 nm, three key mode parameters (effective mode area, gain threshold, and propagation distance) can be determined to be 0.008 2 , 0.5997 µm −1 , and 3309 nm, respectively. Moreover, the figure of merit of the proposed nanolaser is enhanced by almost 2.3 times compared with the model without BP nanosheets. It can be expected that the proposed plasmonic nanolaser shows great potential in exploring ultrahigh density photonic integrated circuit.
