This thesis presents theoretical, simulation and experimental based studies on emission/detection of orbital angular momentum (OAM) beams for the newly emerging integrated OAM photonics technology. The number of applications that utilise the OAM technology has been increasing since the time it has been discovered. Optical communication is one of the high potential applications of OAM beams because of the possibility of providing infinite number of states. This has been considered as the perfect solution for the increasing data load. In order to process the OAM concept in such optical systems, a number of methods have been proposed. In addition to these methods, a new PICs OAM interpretation method has been discussed in this study. The obtained results show that this method has the potential especially for high-capacity optical data transmission. Moreover, the purity of beams (in terms of reflection within the ring resonator) generated by an integrated vortex beam emitter which was proposed by our group-has been investigated for the first time in this study. The investigation showed that there is a disrupting feed-back beam exist within the system. However, its effect on the generated beam's purity is considerably low.
