Monolithic integration of a mode size converter with a laser diode using MOVPE shadow masked growth

In optical communication systems several optical interconnections between semiconductor optoelectronic devices and single mode fibres are required. During the past years, many researchers have focused on the integration of mode size converters with opto-electronic waveguide components, in order to achieve a larger and more symmetric near field pattern at the device facet. Such components allow low coupling losses and large alignment tolerances and hence lower packaging costs. In this paper we present the monolithic integration of a mode size converter with a PBH InGaAsP-InP strained MQW laser diode using the shadow masked growth (SMG) technique.
