This research reports a theoretical investigation on the role of filtered optical feedback (FOF) in the quantum dot light emitting diode (QD-LED). The underlying dynamics is affected by a sidle node, which returns to an elliptical shape when the wetting layer (WL) is neglected. Both filter width and time delay change the appearance of different dynamics (chaotic and mixed mode oscillations ,MMOs). The results agrees with the experimental observations. Here, the fixed point analysis for QDs was done for the first time. For QD-LED with FOF, the system transits from the coherence collapse (CC) case in conventional optical feedback (COF) to a coherent case with a filtered mode in FOF. It was found that the WL washes out the modes which is an unexpected result. This may attributed to the longer capture time of WL compared with that between QD states. Thus, WL reduces the chaotic behavior.

ABSTRACTWe present the fabrication of a Quantum Dot Microcavity Light Emitting Diode (QD-MCLED) emitting at 1.3 μm at room temperature. The long wavelength emission is achieved by using for the first time InGaAs QDs directly grown on GaAs, by metal organic chemical vapour deposition. Electroluminescence bright emission, peaked at 1298 nm with a FWHM of 6.5 meV and a line shape independent on the applied bias is found.

Different Doses

The supplementation of blue light to red light enhanced plant growth compared with the use of red alone. The aim of thestudy was to determine the effect of different doses of blue light on the biometric traits and photosynthesis of dill plants. Theplants were grown in pots in a growth chamber. They were grown in red light (100 μmol m-2 s-1) and blue light (from 10 to 50μmol m-2 s-1) in five combinations. Light emitting diode modules were the source of light. The plants were evaluated every 7days during vegetation, for the first time - seven days after germination and later on the 14th, 21st and 28th day aftergermination. The share of blue light in the spectrum significantly influenced the biometric traits of the dill plants. Itsignificantly inhibited the elongation growth of the plants and negatively affected the increase in fresh weight. A small dose ofblue light (20%) had positive effect on the plants’ area. The research did not reveal a simple relationship between the amountof blue light and dry weight yield. The value of physiological indexes depended both on the combination and measurementtime. The plants from the combination with 30% blue light were characterised by the greatest photosynthesis intensity. Aneffective share of blue light in the spectrum may range from 10 to 30% in relation to red light and depends on the plant’sdevelopment phase and on the result we want to achieve in the cultivation of plants.

AbstractWhen two brief sounds are presented with a short flash of light, we often perceive that the flash blinks twice. This phenomenon, called the “sound-induced flash illusion”, has been investigated as an example of how humans finely integrate multisensory information, more specifically, the temporal content of perception. However, it is unclear whether nonhuman animals experience the illusion. Therefore, we investigated whether the Mongolian gerbil, a rodent with relatively good eyesight, experiences this illusion. The novel object recognition (NOR) paradigm was used to evaluate the gerbil’s natural (i.e., untrained) capacity for multimodal integration. A light-emitting diode embedded within an object presented time-varying visual stimuli (different flashing patterns). The animals were first familiarised with repetitive single flashes. Then, various sound stimuli were introduced during test trials. An increase in exploration suggested that the animals perceived a flashing pattern differently only when the contradicting sound (double beeps) was presented simultaneously with a single flash. This result shows that the gerbil may experience the sound-induced flash illusion and indicates for the first time that rodents may have the capacity to integrate temporal content of perception in a sophisticated manner as do humans.

Abstract The role of die attach adhesive in influencing light output of the white chip-on-board (COB) light emitting diode (LED) emitters is investigated using Monte-Carlo simulations. It is demonstrated for the first time that the use of an optically clear adhesive for replacing conventional adhesive for multiple COB white LED emitters leads to a significant enhancement in light output of up to 22 %. An optimization of packaging materials and process for multiple COB LED emitter to enhance optical efficiency is also studied.
