Passive and hybrid modelocking of a two-section laser diode in an external cavity is investigated. The cavity contains a Fourier transformation that enables spatial separation and individual manipulation of the spectral components for shaping of the pulse spectrum. We achieve 5.5 ps pulses with passiv...
