Design and optimization of high-contrast gratings for multispectral VCSEL-SOI laser sources
Published 2024-08-01“…A simulation model for spectral characteristics calculation is proposed, which includes two heterogeneously integrated parts of the VCSEL: 1) the lower output mirror based on a HCG grating in the silicon layer of the SOI surrounded by air cavities to enhance the contrast of the HCG; 2) the semiconductor VCSEL structure with an air aperture for current and optical confinement. Comparative analysis results of the spectral characteristics of VCSEL-SOI structures for zeroth, first, and second-order modes, which can be excited in the air aperture of the VCSEL, are presented. …”

A novel model of photoacoustic and thermalelectronic waves in semiconductor material
Published 2025-01-01“…The photoacoustic wave creation is independent of the electron–phonon and electron–hole thermalization and results from the thermoelastic stress brought on by the increase in temperature generated by the light. Considering the optical, elastic, and thermoelastic properties of semiconductor material, photoacoustic signals are predicted by solving a thermal diffusion issue and then a thermoelastic problem in sequence. …”
