Abstract
An efficient broadband crystal for wavelength conversion, the crystal being a quasi-phase matched non-linear crystal, having an aperiodic poled structure, each period being tuned, and wherein said tuning varies adiabatically along a length of said crystal from a first end wherein said tuning is a strong negative mismatch to a second end wherein said tuning is a strong positive mismatch or vice versa. The crystal is able to provide efficient wavelength conversion over a range of frequencies.
