Generation and imaging of a tunable ultrafast intensity-rotating...A tunable ultrafast intensity-rotating optical field is generated by overlapping a pair of 20 Hz, 800 nm chirped pulses with a Michelson interferometer (MI). Its rotating rate can be up to 10 trillion radians per second (
Intensity modulation of filaments by shaped laser pulses in fuse... ... shaping the femtosecond laser pulse. The arbitrary control of filamentation intensity has been obtained by the feedback control based on the genetic algorithm, and the peak intensity of filament has changed from about 670 to around 2100 ( ...
Effect of 1070 nm laser intensity on parameters of In0.3Ga0.7As ... ... wave (CW) laser of various intensities. The influences of laser intensity on solar cell parameters extracted by the pollination algorithm were ... cell rose to the maximum and then decreased rapidly in the laser intensity range of 50–900 mW/cm2. With higher
Intensity modulated silver coated glass optical fiber refractive... ... a transducer to get response and feedback from environments, in which optical fibers act as a signal carrier. A novel Ag coated intensity modulated optical fiber sensor based on refractive index changes using IR and UV-Vis (UV-visible) light sources is ...
Generation of intensity difference squeezed state at a wavelengt... ... squeezed state, which means that the fluctuation of the intensity difference between signal and idler beams is less than ... -II phase-matching periodically poled KTiOPO4 crystal operates above the threshold, an intensity difference squeezed state at a telec
Investigation on an all-optical intensity modulator based on an ...An all-optical intensity modulator based on an optical microfiber coupler (OMC) is presented. The modulator works at 1550 nm wavelength and is modulated directly by heating the coupling region with 980 nm pump light injected through the coupling port of ...
Relative intensity noise in high-speed hybrid square-rectangular...Relative intensity noise (RIN) and high-speed modulation characteristics are investigated for an AlGaInAs/InP hybrid square-rectangular laser (HSRL) with square side length, rectangular length, and width of 15,300, and 2 μm, respectively. Single-mode ...
Pulse reference-based compensation technique for intensity-modul...We propose a compensation technique based on pulse reference for intensity-modulated optical fiber sensors that can compensate the power fluctuation of the light source, the change of optical components transmission loss, and the coupler splitting ratio. ...
