Fast wavelength-tunable ultra-violet laser source for confocal Fura-2AM imaging [PDF]
, 2007 We report a novel wavelength-flexible laser source for three-dimensional ultra-violet imaging. Based on supercontinuum generation in photonic crystal fiber, the resultant broadband laser source extended from A = 331 nm into the visible region of the ...

Efficient wavelength conversion and net parametric gain via four wave mixing in a high index doped silica waveguide [PDF]
, 2010 We demonstrate sub-picosecond wavelength conversion in the C-band via four wave mixing in a 45cm long high index doped silica spiral waveguide. We achieve an on/off conversion efficiency (signal to idler) of + 16.5dB as well as a parametric gain of ...

Dual-wavelength domain wall solitons in a fiber ring laser
, 2010 We report on the experimental observation of a new type of dark soliton in a fiber laser made of all normal group velocity dispersion fibers. It was shown that the soliton is formed due to the cross coupling between two different wavelength laser beams ...

Extending device performance in photonic devices using piezoelectric properties [PDF]
, 2013 This study focuses on the influence of epi-layer strain and piezoelectric effects in asymmetric GaInAs/GaAlAs action regions that potentially lead to intra-cavity frequency mixing. The theoretical limits for conduction and valence band offsets in lattice-
