Study of chirp-free operation for guide/antiguide modulator

A method of achieving chirp-free operation of a field-induced guide/antiguide intensity modulator is reported. Both measured and calculated data for chirp-free operation are demonstrated for a 1.15- mu m wavelength. In a push-pull mode of operation, the index in the guide and antiguide regions of th...

Description
Summary:A method of achieving chirp-free operation of a field-induced guide/antiguide intensity modulator is reported. Both measured and calculated data for chirp-free operation are demonstrated for a 1.15- mu m wavelength. In a push-pull mode of operation, the index in the guide and antiguide regions of the modulator change in opposing directions, which can be adjusted such that the resulting phase shift contributions to the guided mode cancel each other, resulting in zero net mode phase shift.< >
