The limits of isolation and bandwidth for existing waveguide isolators in InP are analyzed. A new integrated waveguide isolator design is proposed which achieves an isolation greater than 38 dB and a loss of 1.4 dB.
The monolithic integration of components holds promise to increase network functionality and reduce packaging expense. Integration also drives down yield due to manufacturing complexity and the compounding of failures across devices. Consensus is lacking on the economically preferred extent of integration. Previous studies on the cost feasibility of integration have used high-level estimation methods...
