Abstract:For many novel integrated WDM-devices such as multi-wavelength lasers (MWL), the integration of passive waveguides and active devices is required. Several techniques such as butt coupling, shadow mask growth or selective area growth have been proposed for realising monolithic integrated photonic integrated circuits (PIC). Whatever integration scheme is used, it requires a lot more processing steps compared to the realisation of a standard laser or a passive waveguide device. As a consequence the fabrication of… Show more
