Infrared-to-visible upconversion: spontaneous emission and amplified spontaneous emission in a ZBLAN:Er3+ optical fiber
infrared-to-visible upconversion
2011/5/4
Careful, intensity and spectral examinations of fluorescence in the process of infrared-to-visible upconversion, observed perpendicularly to the excited ZBLAN:Er3+ optical fiber (side fluorescence), a...
Coherent photon transport from spontaneous emission in one-dimensional waveguides
photon transport spontaneous emission one-dimensional waveguides
2015/8/11
A two-level system coupled to a one-dimensional continuum is investigated. By using a real-space model Hamiltonian, we show that spontaneous emission can coherently interfere with the continuum modes ...
Wide spectra characteristics of gain and carrier-induced refractive index change from measured amplified spontaneous emission spectra
traveling-wave semiconductor optical amplifier wide spectra characteristics
2011/4/26
Based on our derived analytical equation directly relating small signal gain (SSG) with amplified spontaneous emission (ASE) of traveling-wave semiconductor optical amplifier (TWA), SSG spectra in an ...
High Extraction Efficiency of Spontaneous Emission from Slabs of Photonic Crystals
High Extraction Efficiency Spontaneous Emission Slabs Photonic Crystals
2015/8/12
A thin slab of two-dimensional photonic crystal is shown to alter drastically the radiation pattern of spontaneous emission. More specifically, by eliminating all guided modes at the transition ...
