Trommer, D.D.Trommer2022-03-092022-03-091995https://publica.fraunhofer.de/handle/publica/325346After a brief review of realised photonic integrated circuits (PICs), the fundamental technological problems of photonic integration on InP and their solutions are discussed. A versatile fabrication process is described and results on PICs fabricated with this process are presented. Finally some prospects of future devices and technologies are given.eniii-v semiconductorsindium compoundsintegrated optoelectronicsoptical fabricationoptical receiversreviewsphotonic integrated circuitsreviewphotonic integrationinpfabrication process621conference paper
