Optical Network on Chip (ONoC) is being researched for integrating no of cores on a single chip or die. As there are some subsisting topologies of optical interconnect for ONoC, multi segment bus (MSB) is one them in which cluster of cores are interconnected in optical domain. Along the signal path of these topologies, signal losses and crosstalk component takes into account. MSB topology results in reduction of signal power and signal to noise ratio also decreases. This paper presents simulation and analysis of a 16 cluster topology. The design of multi segment bus is made by considering the losses due to various fundamental components used in the topology and uniformity of the components while placing them in the design. In design of photonic circuit, system requires micro ring resonators (MRRs) as modulators, and photodetectors with clear cognizance on the resonance behavior of the ring resonator. Inter segment routers (ISRs) couples light at a particular wavelength between two parallel waveguides.
