Near-Infrared Ultrawide Bandwidth LEDs Using InAs Quantum Dots of Equally Tuned Heights
Bibliographic record
Abstract
Ultrawide bandwidth light-emitting diodes (LEDs) using eight layers of InAs/GaAs quantum dots (QDs) of equally tuned heights are reported. Tilted and tapered waveguides of various dimensions are tested under continuous-wave operation conditions. An emission spectrum with 3-dB bandwidth up to 173 nm at a peak wavelength of 1064.5 nm is achieved. The measured emission spectra of the QDs-LEDs as a function of the injection current indicated that the obtained large bandwidth is related to the contribution of the excited states (p, d) from the ensemble of the dots to the recombination mechanism. Continuous-wave output power of 0.6 mW is measured in the corresponding device that is made of a 1-mm-long waveguide and with tilted and tapered angles of 6° and 2°, respectively.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
