GaAs deep-center stimulated-emission at 1.5µm
2010 Edition, May 1, 2010 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Room-temperature stimulated-emission, optical gains larger than known significant losses, and single-pass laser action from GaAs deep-centers are demonstrated at low electrical injection in cw mode at 1.3-1.5µm. Fast hole capture maintains the...

Stimulated emission depletion with sub-ns pulses
2003 Edition, January 1, 2003 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We have designed a new stimulated emission depletion microscope that applies longer STED pulses (>100 ps) than commonly used (5-10 ps). It is found that longer pulses have a positive effect on photostability of the fluorescent molecules. Utilizing ultrafast shutters, the recovery of...

Hybrid photonic-plasmonic resonances to control spontaneous and stimulated emission
2017 Edition, June 1, 2017 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

By hybridizing plasmonic and photonic resonators one can realize narrow bandwidth structures with plasmonic-like field enhancements. I will present our progress in understanding the hybridization physics and realizing control of spontaneous and stimulated...

Transient THz stimulated emission from silicon pumped by FELs
2017 Edition, August 1, 2017 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Transient-type stimulated emission in the terahertz frequency range has been achieved from silicon crystals doped by phosphorus and bismuth donors under optical excitation by a few picosecond-long pulses generated by the infrared free electron lasers, FELIX...

Stimulated emission on sodium D-lines using broadband optical pumping
2017 Edition, June 1, 2017 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This paper considers the issue how to obtain the amplification of stimulated emission in the cell with sodium vapor using a longitudinally pumped dye laser arrangement at a line shorter than the transitions from the ground state to the levels D 1 and D 2 ....

Stimulated emission of SPPs on top of hyperbolic metamaterials
2014 Edition, June 1, 2014 - Optical Society (The) (OSA)

We show that the stimulated emission of surface plasmon polaritons on top of lamellar metal/dielectric metamaterial has much lower threshold than on top of silver.

Stimulated emission from bulk field-ionized GaAs
1968 Edition, Volume 4, April 1, 1968 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

High-field domains passing through n -type gallium arsenide pulsed above a critical field produce electron-hole pairs by impact ionization, resulting in emission of recombination radiation of band gap energy. Specimens have been made in a configuration that allows intense...

Stimulated Emission From Semiconductor Microcavities
1997 Edition, January 1, 1997 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Quest for low-threshold stimulated emission of surface plasmons polaritons
2013 Edition, June 1, 2013 - Optical Society (The) (OSA)

The stimulated emission threshold of SPPs can be reduced by an order of magnitude if the operation range is changed from visible to near-IR and metamaterial substrates are used instead of silver films.

Plasmon stimulated emission in arrays of bimetallic stripes
2010 Edition, May 1, 2010 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Plasmon stimulated emission gives rise to coherent emission of leakage radiation from adjacent stripes in arrays of bi-metallic structures coated with dye-doped dielectric. This resulted in unambiguous interference patterns imaged by Fourier-plane leakage...
