Laser beam shaping is a key element in achieving better accuracy and resolution. Currently, there are two main methods for shaping a beam: one method uses two lenses to output a homogeneous beam with no power control. This method requires time consuming calibration of the lenses and can not accept o.....

A major problem related to the use of photonic resonators in optical systems is the accuracy of setting the resonance wavelength. Fabrication imperfections and environmental effects such as temperature change may cause deviations from the desired resonance wavelength.This deviation can be compensate.....
