High capacity terahertz frequency combs generated by small scale optical mesh network

Abstract

A novel design of mesh ring resonator system is proposed and simulated to obtain the multi frequency comb bands, in which the frequency band less than 10 GHz (about 0.084 nm) of comb lines spacing with commercialized ring parameters is achieved. The proposed system is used to enhance the capacity of optical frequency comb for redundancy networks against the network element failures and to increase the survivability of the communication systems. The dependence of the mesh ring transmission characteristics with coupling coefficients of directional couplers is analyzed and studied. In application, such a system can be employed as an on-chip optical device for redundancy networks against the network element failures and to increase the survivability of the communication systems. The potential for improving the reliability and availability of the optical networks is discussed. Moreover, the proposed system can also be employed as multi sensing devices, where the microscale, for instance, as an atom/molecule force sensor can be measured by the shifted parameters of the Vernier filters. © 2014 World Scientific Publishing Company.
