On-chip frequency comb generation at visible wavelengths via simultaneous second- and third-order optical nonlinearities.

Microresonator-based frequency comb generation at or near visible wavelengths would enable applications in precise optical clocks, frequency metrology, and biomedical imaging. Comb generation in the visible has been limited by strong material dispersion and loss at short wavelengths, and only very narrowband comb generation has reached below 800 nm. We use the second-order optical nonlinearity ...

Optimization of Resonant Second- and Third-Order Nonlinearities in Step and Continuously Graded Semiconductor Quantum Wells

Methods for systematic optimization of step-graded and continuously graded ternary alloy based quantum wells (QW’s), in respect to secondor third-order intersubband nonlinear susceptibilities at resonance, are discussed. The use of these methods is examplified on the design of AlxGa1 xN and AlxGa1 xAs-based QW’s intended for resonant second harmonic or third harmonic generation with h! = 116 me...

New potentials for the laser crystals with second and third optical nonlinearities

Two-dimensional solitons with second-order nonlinearities.

We investigate the propagation of intense Gaussian beams in materials with quadratic nonlinearity. Excitation of (2 + 1) solitons is numerically predicted at finite phase mismatch and in the presence of linear walk-off between the fundamental and second-harmonic waves. The numerical results are interpreted in terms of the conserved quantities of the wave evolution, and the appropriate condition...
