Abstract

The foremost emphasis of this foundational research letter has been given on analytical investigation of an enhanced simulative study on shortwave infrared gains (SWIRGs) of In_0.68Al_0.08Ga_0.24As/InP lasing nanoscale heterostructure for fiber optic cable communication applications under transverse electric and magnetic bi-modes at 300K. In the starting of this work, taking into account recent and emerging computational technology, an enhanced and improved effective mass theory for single and multi-sub-bands has been utilized to enumerate the appropriate SWIR gain parameters as well as electrons-holes (Es-Hs) levels of quasi-Fermi energies. Under advanced simulation, first of all, the salient computational performances of Es-Hs levels of quasi-Fermi sub-band energies versus injected carriers (10¹⁸ cm^-3) at 300K have been analysed simulatively. Next, electric and magnetic transverse bi-modes induced several spectral performances of SWIR-gain with wavelengths of photons have also been investigated analytically. In spite of this, the prominent performances of SWIR-differential gain (10^-16cm²) with injected carriers (10¹⁸ cm^-3) under transverse electric and magnetic bi-modes at 300K have been analyzed dominantly. Throughout the results, the peak intensities of SWIR-gain are achieved at wavelengths 1330 nm and 1550 nm corresponding to two crests of SWIR-spectra respectively under transverse bi-modes. Consequently, this emitted SWIR light gain by In_0.68Al_0.08Ga_0.24As/InP heterogeneous nanostructure of wavelengths ~ 1330 nm and 1550 nm can be substantially utilized in the applications of fiber optic cable communications in the transmission of SWIR-signals through the modern process of total internal reflection with minimal attenuations of SWIR-signals (in dB × km^-1) owing to lowest fiber dispersions and fiber absorptions.
