Abstract :
For the first time an external cavity laser diode whose operating wavelength is controlled by an array of vertical electro-absorption modulators (EAM) is successfully demonstrated. It provides wavelength switching, intensity modulation und multiple wavelengths lasing due to purely electronical control of the EAMs. Fast on-off switching as well as wavelength switching on a ns-timescale are achieved.
