“…Since many of the optical, diffusion and gain parameters are temperature dependent, it is also necessary to know the exact temperature distribution within the semiconductor structure. To analyze the optical properties of our structure, we used the effective frequency method (EFM) [21,22]. To find the optimal design of the active region, we applied the 1-dimensional carrier transport model [23].…”

“…From the fit, the extracted T 0 is 83.0 K in the measured range (78-300 K), which is comparable to previously reported semiconductors. [46][47][48] The threshold rising exponentially may be ascribed to the thermal population of the optical phonon branch.…”

densities, long carrier diffusion lengths, high photoluminescence quantum yield (PLQY), tunable direct bandgap, and low Auger recombination rate. [11][12][13][14] With these unique properties, a tide of intensive research on organic-inorganic halide perovskite-based amplified spontaneous emission (ASE)/laser, including but not limited to thin-film, has been conducted with the excitation of optical pumping sources. [15,16] In addition to the aforementioned medium, colloidal nanocrystals of cesium lead halide perovskites have also drawn tremendous attention due to their high stability upon exposure to optical pumping, thermal stress, and moisture. [17] At the same time, the quantization of electron energy levels of nanocrystals also contributes to narrow emission width. Since the first report on ASE from CsPbBr 3 nanocrystals, all-inorganic perovskites nanocrystals (CsPbX 3 , X = Cl, Br, I) have been dramatically developed. In particular, bandgap energies are precisely and continuously controlled through compositional regulation (mixed halide Cl/Br and Br/I) as well as quantum-size effects. [17] Another key practical advantage of CsPbX 3 nanocrystals is the easy realization of emission covering a blue-green spectral region (410-530 nm) through facile synthesis. [18] As a comparison, only an extremely small (≤5 nm) size for common metal chalcogenide nanocrystals such as CdSe can contribute to being an approach to the blue-green region; even then, the PLQY is rather low (≤5%) owing to the mid-gap trap states. [17] ASE wavelength is also tunable from visible range to near-infrared spectral range by integrating the facile processability with the merits of quantum confinement. [17] Further, CsPbX 3 nanocrystals are easy to mix with other optoelectronic materials (polymers, optical glass, and nanomaterials) for further adjustments of optical properties and application in various environments.Optical glass is an excellent medium for optical storage, amplification, and waveguide used in society, industry, and scientific research, mainly due to its unequaled optical transparency as well as prominent mechanical, chemical, and thermal resistance. [1,9,[19][20][21][22][23] The improvement and optimization of optical property are achievable by the introduction of homogeneously distributed phosphor particles/semiconductor nanocrystals in a glass matrix via embedment and/or crystallization (nucleation and crystal growth). [9,[19][20][21] In addition, the phosphors/nanocrystals inside the glass have high chemical and physical stability owing to the insulation of glass to the external moisture,The diverse optoelectronics systems can provide interesting design inspiration for photonics devices, ranging from optical modulators to light-emitting displays. With the increasing applications and requirements of optical interconnect in complex environments, an essential operation is increasingly being pursued to exploit the consolidation of various merits of basic components. Here, an optical gain from monodisperse CsPbBr 3 quantum dots cr...

“…The number of iterations is usually significantly larger than the number of repetitions due to the thermal effects. Therefore, the thermal computations can be intermixed with the electrical computations and it is sufficient that the temperature distribution is updated once every 10-20 electrical iterations [33].…”

Impact of an Antiresonant Oxide Island on the Lasing of Lateral Modes in VCSELs

Use of antiresonant structures is a proven, efficient method of improving lateral mode selectivity in VCSELs. In this paper, we analyze the impact of a low-refractive antiresonant oxide island buried in a top VCSEL mirror on the lasing conditions of lateral modes of different orders. By performing comprehensive thermal, electrical, and optical numerical analysis of the VCSEL device, we show the impact of the size and location of the oxide island on the current-crowding effect and compute threshold currents for various lateral modes. If the island is placed close to the cavity, the threshold shows strong oscillations, which for moderate island distances can be tuned to increase the side mode discrimination. We are therefore able to pinpoint the most important factors influencing mode discrimination and to identify oxide island parameters capable of providing single-lateral-mode emission.
