All-fiber self-calibrating polarization synthesizer.

Self-calibrating binary polarization analyzer.

We report a self-calibrating polarization analyzer fabricated with binary magneto-optic polarization rotators. The device automatically overcomes wavelength and temperature dependent inaccuracies and has impressive state of polarization and degree of polarization accuracies of 0.3 degrees and +/-0.5%, respectively, from 1460 to 1580 nm.

Self - starting all - polarization maintaining Yb - fiber laser with a polarization maintaining anomalous dispersion higher - order - mode fiber

Self-starting self-similar all-polarization maintaining Yb-doped fiber laser.

We report on the generation of self-similar pulses from an self-starting saturable absorber mirror (SAM) based environmentally stable fiber laser comprising only polarization maintaining (PM) fibers. Pulse energies of 1 nJ at a repetition rate of 17 MHz were obtained, which could be externally compressed to an autocorrelation width of 280 fs.

Calibrating CMB Polarization Telescopes

Instruments for measuring the polarization of the cosmic microwave background (CMB) must be designed for accuracy as well as precision. The requirement for precision translates into a need for detectors with unprecedented sensitivity. Accuracy requires good methods for calibrating the response of the instrument to small polarized signals superimposed on large unpolarized signals. Since well-cha...

All-Fiber Bismuth Doped Self-Sweeping Laser

Figure 1: Laser wavelength dynamics The effect of self-induced laser line sweeping (or self-sweeping) was discovered in ruby laser in 1962 [1]. It was considered as an undesirable effect due to a small sweeping range. In fiber lasers the effect with broad sweeping range (more than 10 nm) was observed almost 50 years later [2]. The self-sweeping effect is caused by the formation of dynamical pha...
