Increased wavelength coverage in nonlinear optics by nonuniformly chirped quasi-phase-matching

A nonlinear crystal has increased spectral acceptance. The nonlinear crystal includes a plurality of domains. The domains are arranged serially across the nonlinear crystal. The domains have alternating polarity. The poling periods of the domains are varied across the nonlinear crystal so as to prov...

More Information
Summary:A nonlinear crystal has increased spectral acceptance. The nonlinear crystal includes a plurality of domains. The domains are arranged serially across the nonlinear crystal. The domains have alternating polarity. The poling periods of the domains are varied across the nonlinear crystal so as to provide nonuniform chirping of phase matching of focused optical signals propagated through the nonlinear crystal.
