“…A first paper investigating the modularity of an integrated-optics architecture based on directional couplers [24], appears in 2000: in the work a recursive design technique is proposed. In 2001, another similar study [25] reports a recursive technique to design the stages of a multistage network, independently on the technology of the switching elements; little attention is however dedicated to the interconnection of the stages. Meanwhile, in [26] an analogous approach is adopted to design MEMS-based stages.…”

I. INTRODUCTIONT HE optical implementation of Optical Multistage Switching Networks (OMSNs) has been widely studied by researchers. Several architectures have been studied, proposing various implementations based on different transmission media (including fiber, waveguide and free-space optics) and relying upon various types of components (e.g., MEMS, microring resonators, directional couplers, etc.) used as switching elements.Recently, research on Optical interconnections is casting new light on optical switching, and in particular on OMSNs. Optical interconnections is the conventional term that indicates the usage of photonic systems to interconnect several optoelectronic high-speed transmitters and receivers located at short distance from one another. "Short" means in general the range of distances separating subsystems within a system, and

“…So far Wavelength Division Multi-plexing (WDM) technology also has contributed to the higher transmission bandwidths [5][6][7][8]. In particular, photonic switching technologies are concerned to use in practice Photonic Packet Switching or Photonic Burst Switching of Time Division Switching [9][10][11][12][13][14][15][16]. In addition, Space Division Switching devices such as MEMS also are promising and are developed by many researchers [17][18][19][20][21][22][23][24].…”

Pair control is generally adopted in telecommunication systems to save software processing time to set up both-way paths between a sender and a receiver. We have introduced new pair control architecture into a Photonic Switch Fabric (PSF) which is a key instrument of a developed Photonic Label Switch Router (PLSR). In our WAPS (Wavelength Assignment Photonic Switching System), the PLSR is to be operated as a photonic router in the optical internet system to guarantee QoS (Quality of Service) and the transmission bandwidth by providing end-to-end wavelength LSPs (Label Switched Paths). In contrast with that conventional pair controlled PSFs do not have capability to save switching elements and its control circuits, the proposed architecture enables to save them drastically.

“…In order to measure crosstalk, a common approach is to consider the worst case in which all connections are active at the same time. Moreover, crosstalk originating in the interstage interconnections due to optical beam intersection is usually negligible [26]: only power leakage in non-ideal SEs is thus considered. When two connections are active at the same time in the two channels switched by a 2 × 2 SE, each of them receives a so called first-order crosstalk contribution.…”
