Second Harmonic Generation of a Gaussian Beam Wave Optics.

To the square of the waveguide length for undepleted pumps. In lossy waveguides, the attenuation at both fundamental and second-harmonic wavelengths results in most of the second harmonic SH power inside the waveguides being generated near the input end of the waveguide but most of the SH power exiting the waveguide being generated close to the. Harmonics are voltages or currents that operate at a frequency that is an integer whole-number multiple of the fundamental frequency. So given a 50Hz fundamental waveform, this means a 2nd harmonic frequency would be 100Hz 2 x 50Hz, a 3rd harmonic would be 150Hz 3 x 50Hz, a 5th at 250Hz, a 7th at 350Hz and so on. Based on this, efficient second-harmonic generations SHG were revealed at the fundamental wavelength of = 1.55 m with good field confinement. The SHG efficiency, as well as the coupling coefficient and mode area, were analyzed and discussed in detail with respect to the structural parameters. #169; 2011 Optical Society of America.

Second harmonic generation SHG, also called frequency doubling, is a nonlinear optical process, in which photons interacting with a nonlinear material are effectively combined to form new photons having twice the frequency of initial photons. SHG was firstly demonstrated by Franken and his colleagues in 1961 Franken et al., 1961.
