Lead chalcogenide IR-emitters and detectors on Si-substrates

Moldavian Journal of the Physical Sciences, 2006
Narrow gap IV-VI (lead chalcogenide) compounds are employed since long time as mid-IR-detectors and -lasers. IV-VIs are tolerant to structural defects (dislocations).

COMPARISON BETWEEN THE INFLUENCES OF LAYER THICKNESSES AND ALAS MOLE FRACTION-X ON VERTICAL-CAVITY SURFACE-EMITTING LASERS

, 1993
Based on the n(x, lambda), the calculation of the reflection spectrum for vertical cavity surface emitting lasers shows that the deviation of the central wavelength caused by the change of layer thickness is much more than that caused by the change of ...

Far-field and beam characteristics of vertical-cavity surface-emitting lasers

, 1996
We have determined the far-field patterns and beam parameters of vertical-cavity surface-emitting lasers (VCSELs) with different structures. The results show that the window diameter and the active-layer aperture of VCSELs strongly influence laser far ...

Effect of Laser Posterior Nasal Neurolysis for the Treatment of Chronic Rhinitis: A Randomized Controlled Trial

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background To determine the safety and efficacy of laser ablation of the posterior nasal nerve (PNN) for the treatment of chronic rhinitis. Methods This study was a single‐center, prospective, single‐blinded, randomized sham‐controlled trial. Patients with a 24‐h reflective Total Nasal Symptom Score (rTNSS) ≧ 5, rhinorrhea ≧ 2, and congestion ≧
