spontaneous emission उदाहरण वाक्य

On the one hand SLEDs are semiconductor devices that are optimized to generate a large amount of amplified spontaneous emission ( ASE ).
As described above, superluminescent light emitting diodes are based on the generation and on the amplification of spontaneous emission in a semiconductor waveguide.
Controlling the rate of spontaneous emission and thus raising the photon generation efficiency is a key requirement for quantum dot based single-photon sources.
In the case of emitters, the cavity modifies the spontaneous emission of light-emitting diodes ( LED ) improving their spectral purity and directivity.
This infinite degree of freedom for the emission of the photon results in the apparent irreversible decay, i . e ., spontaneous emission.

The optical power emitted by semiconductor active devices is always affected by fluctuations ( intensity noise ) that are induced by the spontaneous emission.
After a statistically sufficient quantity of time, an electron in an excited state will undergo a transition to a lower state via spontaneous emission.
It gave nonintuitive predictions such as that an atom's spontaneous emission could be driven by field of effectively constant frequency ( Rabi frequency ).
An atom can be absorption of a photon with sufficient energy, or decay to a lower energy state through spontaneous emission of a photon.
It gave the nonintuitive prediction that the rate of spontaneous emission could be controlled depending on the boundary conditions of the surrounding vacuum field.
