Evidence for stimulated emission in silicon nanocrystal microspheres
2005 Edition, January 1, 2005 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Silicon has been used in all photonic functions except lasing. We report evidence for stimulated emission in silicon nanocrystal microspheres under strong pulsed excitation.

Depletion dynamics for stimulated emission depletion (STED) microscopy
2008 Edition, May 1, 2008 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We present preliminary experimental data revealing depletion dynamics for stimulated emission depletion (STED) microscopy as a function of excitation intensity, depletion intensity, time delay, and fluorophore damage. FluoSpheres 350/440(invitrogen) is used.

Directional stimulated emission from deformed GaN micropillar cavities
1999 Edition, Volume 2, January 1, 1999 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Whispering gallery mode (WGM) lasers hold promise because of their high Q and low thresholds. Their drawback, however, is the lack of directional emission. Deformed cavities support both regular and chaotic orbits that have emission directionality. Recent work...

Amplified stimulated emission of sub-wavelength gratings integrated VCSEL
2006 Edition, May 1, 2006 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We demonstrate the monolithic integration of a VCSEL half-cavity and a single-layer sub-wavelength grating as its top mirror. Polarization-selective amplified stimulated emission with selection ratio of 20 dB was obtained.

Lasing and stimulated emission in /spl pi/-conjugated polymers
2000 Edition, Volume 36, January 1, 2000 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Recent studies of lasing and stimulated emission in luminescent /spl pi/-conjugated polymers performed by our group are presented. Optical properties of cylindrical high-Q polymer microcavities are discussed. The emission spectra of plastic microring...

Stimulated emission from co-doped zinc-aluminosilicate glass ceramics
2005 Edition, January 1, 2005 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Glass ceramic materials containing tetrahedral divalent cobalt ions have been recently introduced as laser saturable absorbers. Here we present study of stimulated emission from co-doped zinc-aluminosilicate glass ceramics (Co:ZAS).

A Practical Superheterodyne-Receiver Detector Using Stimulated Emissions
2011 Edition, Volume 60, April 1, 2011 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The accurate and timely discovery of radio receivers can assist in the detection of radio-controlled explosives. Superheterodyne receivers emit low-power radio signals during normal operation. These are known as unintended emissions. In this paper, the unintended...

Long-wavelength stimulated emission in HgCdTe quantum well waveguide heterostructures
2016 Edition, September 1, 2016 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We report on stimulated emission (SE) at wavelengths up to 10.2 μm from waveguide HgCdTe structures with several quantum wells (QWs) inside the waveguide core. The onset of the SE takes place under optical pumping with intensity as low as 0.12 kW/cm2...

Stimulated emission dynamics in self-assembled InAs/GaAs quantum dots
2000 Edition, January 1, 2000 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Summary form only given. Self-assembled semiconductor quantum dots have found interest as gain materials for semiconductor lasers. While time-resolved studies on quantum dots have mainly focused on the spontaneous recombination dynamics, little is known about the dynamics of...

Anomalous magneto-plasmonic spectra: evidence for stimulated emission or superradiance?
2005 Edition, Volume 2, January 1, 2005 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Novel magneto-plasmonic emission phenomena are observed from excited Landau levels in In/sub x/Ga/sub 1-x/As quantum wells when pumped using intense femtosecond laser excitation in strong magnetic fields (25 T). The emission...
