Mode transition in complex refractive index coated single-mode–multimode–single-mode structure
(Optical Society of America, 2013)
Artículo / Artikulua,
By coating a single-mode–multimode–single-mode (SMS)
structure with a high refractive index thin-film it is possible to obtain a
transition of modes for specific combinations of thin-film thickness, thinfilm
refractive ...
BOTDA measurements tolerant to non-local effects by using a phase-modulated probe wave and RF demodulation
(Optical Society of America, 2013)
Artículo / Artikulua,
We demonstrate a Brillouin optical time domain analysis sensor based on a phase modulated probe wave and RF demodulation that provides measurements tolerant to frequency dependent variations of the pump pulse power induced ...
