Control of the formation and amplification of pulse bursts in regenerative amplifiers
IET Control Theory & Applications, 2023 This paper presents control strategies to generate bursts of high‐intensity laser pulses with arbitrary envelope from regenerative amplifiers by suitably adjusting the energy of the injected seed pulses. To this end, existing and experimentally validated

Advanced Functional Materials, EarlyView.This work discusses the use of blended channel materials in OECTs. It explores how mixing glycolated and alkoxylated polymers in various ratios offers a simpler and more efficient route to tuning OECT properties. The performance of the polymer blends is compared to the corresponding copolymers, demonstrating similar OECT characteristics, swelling ...

Time-resolved spectra of a self-pulsing quantum dot laser [PDF]
, 2010 Self-sustained pulsations in the output of an InAs quantum dot laser diode in the MHz range are reported for the first time. The characteristics (shape, range and frequency) are presented for the free running laser and when optical feedback in the ...

Advanced Functional Materials, EarlyView.Novel ferrocene derivatives (e.g., FcPhc2) are used as an ultrathin layer hole‐blocking layer, reducing hole injection from the Ag contact. This results in an ultralow noise spectral density of 1.2 × 10−14 A Hz−1/2, and a high specific detectivity of 8.1 × 1012 Jones at −0.5 V.
