Optical space switches are key elements for the next generation of switching fabrics in backbone routers, high performance computing systems, and large data processing and storage systems. A number of architectures and alternative options for gating elements have been proposed, assessed, and implemented for a limited port count. The challenge is to further enhance the scalability and energy efficiency of space switches to support future traffic loads. This paper proposes a heterogeneous implementation of the space switches based on two different types of gating elements, namely semiconductor optical amplifiers (SOA) and Mach-Zehnder Interferometers (MZI). With respect to the existing homogeneous implementations, a higher energy efficiency can be achieved by minimizing the number of SOAs, but crosstalk is introduced by MZI. To reduce the power consumption while still guaranteeing adequate physical layer performance, the design of both Spanke and multi-stage architectures is optimized by strategically placing the different gating and amplification elements, and a physical layer analysis is carried out to validate the performance. The proposed heterogeneous implementation is able to achieve power savings up to 10% and 50% in the Spanke and multi-stage Beneš architectures, respectively, with respect to SOA-based space-switch implementations. Moreover, an improvement of the physical layer performance is achievable in the Spanke architecture thanks to the different placement of the SOAs.Index Terms-Energy efficiency, Mach-Zehnder interferometer (MZI), optical interconnection networks, power consumption, semiconductor optical amplifier (SOA), space switch.

“…The upper index in the sum in (17) represents the maximum number of conversions that can occur for the packets arriving on a generic wavelength k and directed to the first (jÀ1) OLs selected by the control unit; this index is equal to (jÀ1)F(MÀ1), where F(MÀ1) is the maximum number of conversions required by any OI. In order to evaluate p W tot;k;jÀ1 ðkÞ it is necessary to observe that W tot,k,jÀ1 is given by the sum of the number of conversions required by the first (jÀ1) OIs selected before the target OI.…”

“…In fact recently arrays of 32 SOAs have been shown to be feasible [17], and it is reasonable to think that in a short time these devices will be available with a relative low cost, while due to technological constraints the cost of available optical TWCs will be very high. (iv) This evaluation only takes cost into account.…”

“…The optical side of the switch uses the SOA-based optical switches, as the SOA technology can support less than microsecond level switching speed. A typical architecture of such a SOA switch is given in [18]. However, the details of the optical side architecture is beyond the scope of this paper.…”
