Recombination processes in intrinsic and p-doped low-threshold 1.3 µm InAs-based quantum dot lasers on silicon
<p>Data for the paper with the following abstract.</p> <p>On-chip lasers are a key component for the realization of silicon photonics. The performance of silicon-based quantum dot (QD) devices is approaching equivalent QDs on native substrates. To drive forward design optimization we investigated the temperature and pressure dependence of intrinsic and modulation p-doped 1.3 μm InAs dot-in-well (DWELL) laser diodes on on-axis silicon substrates for comparison with devices on GaAs substrates. The silicon-based devices demonstrated low room temperature (RT) threshold current densities (<em>J<sub>th</sub></em>) of 192 Acm<sup>-2</sup> (538 Acm<sup>-2</sup>) intrinsic (p-doped). Intrinsic devices exhibited temperature stable operation from 170-200 K. Above this, <em>J<sub>th</sub></em> increased more rapidly due to increased non-radiative recombination. P-doping increased the temperature at which <em>J<sub>th</sub>(T)</em> started to increase to 300 K with a temperature insensitive region close to RT, but with a higher <em>J<sub>th</sub></em>. A strong correlation was found between the temperature dependence of gain spectrum broadening and the radiative component of threshold <em>J<sub>rad</sub>(T)</em>. At low temperature this is consistent with strong inhomogeneous broadening of the carrier distribution, which is more pronounced in the p-doped devices. At higher temperatures <em>J<sub>th</sub></em> increases due to homogeneous thermal broadening coupled with non-radiative recombination. Hydrostatic pressure investigations indicate that while defect-related recombination dominates, radiative and Auger recombination also contribute to <em>J<sub>th</sub></em>.</p>

Structurally induced tuning of the relative sensitivity of LaScO3:Cr3+ luminescent thermometers by co-doping lanthanide ions
<p>Ratiometric luminescence thermometry for remote temperature sensing has been constantly gaining an increasing popularity due to its simplicity with yet high precision. Transition metal ions still have an underestimated potential in that area as their luminescence properties can be tuned by targeted modification of the host compound. In this work, we demonstrate that concept in the phosphor LaScO<sub>3</sub>:Cr<sup>3+</sup> by co-doping with various lanthanide ions that partially substitute the La<sup>3+</sup> ions of the host. It is demonstrated that the incorporated lanthanide ions affect the bond lengths of the [CrO<sub>6</sub>]<sup>9-</sup> octahedra in the structure and thus, have a subtle impact on the local crystal field around the Cr<sup>3+</sup> ions. The changes in the crystal field strength lead to a variation in the energy gap between the thermally coupled <sup>2</sup>E<sub>(</sub><em><sub>g</sub></em><sub>)</sub> and <sup>4</sup>T<sub>2(</sub><em><sub>g</sub></em><sub>)</sub> states of Cr<sup>3+</sup>, which affects the thermal quenching behavior of the related 3d<sup>3</sup>-3d<sup>3</sup> luminescence. This has an immediate consequence for the potential future use of Cr<sup>3+</sup> together with lanthanide ions in a ratiometric luminescence thermometry and allows to selectively tune the performance of this structurally sensitive ion.</p>
Spectral and thermometric properties altering through crystal field strength modification and host material composition in luminescent thermometers based on Fe3+ doped AB2O4 type nanocrystals (A= Mg, Ca; B=Al, Ga)
<p>The growing interest in the use of luminescence thermometry for noncontact temperature reading in very specific conditions imposes the need to develop an approach allowing modification of the luminescence parameters of the thermometer accordingly to the requirements. Therefore, in response to these expectations, this manuscript reports an approach to modulating the spectral position and the luminescence thermal quenching rate of Fe<sup>3+</sup> ions by modifying the crystal field strength and the host material composition of nanocrystalline AB<sub>2</sub>O<sub>4</sub> type nanocrystals (A= Mg, Ca; B=Al, Ga). It was proved that in a group of MgAl<sub>2</sub>O<sub>4</sub>, MgGa<sub>2</sub>O<sub>4</sub>, CaAl<sub>2</sub>O<sub>4</sub>, and CaGa<sub>2</sub>O<sub>4</sub> nanocrystals doped with Fe<sup>3+</sup> ions the emission spectral range, as well as the relative thermal sensitivity (from 0.2%/<sup>o</sup>C for MAO to 2.07%/<sup>o</sup>C for CGO) and the operating temperature range, can be easily modified by the host material composition. For instance, a maximal relative thermal sensitivity of 2.58%/<sup>o</sup>C is obtained for Fe<sup>3+</sup>, Tb<sup>3+</sup> co-doped CaAl<sub>2</sub>O<sub>4 </sub>nanocrystals. The proposed approach is a step toward the intentional designing of the highly sensitive luminescent thermometer.</p>
