“…The proposed HCROS architecture was optimized and a certain number of OSEs were reduced [25]. By reducing the number of OSEs we can achieve a more compact footprint for the optical switch and a reduction in OSEs also minimizes the power consumption and IL caused due to the drop/bar state of OSEs, which consume more power in the drop/bar state than the through/cross state [38].…”

“…The non-blocking property of the proposed HCROS architecture is a necessary requirement. Here, we prove the non-blocking property of the proposed HCROS by using transfer matrix approach, which is used in a lot of research work to model a multi-stage optical switch [17], [25]. To prove the non-blocking feature of proposed 6-port HCROS, a theorem is presented as follows:…”

“…Designing optical switch architecture with an optimum number of OSE can minimize overall insertion loss and power consumption in the network topology [21]. Numerous methodologies have been proposed to construct optical switch/router topologies with optimal arrangements of OSEs and different methods have been proposed to optimize the number of OSEs to improve overall network performance [22][23][24][25][26]. In this regard, several multi-stage blocking, strictly non-blocking (SNB), and rearrangeable non-blocking (RNB) optical switch architectures have been presented [27,28], e.g., Benes [29], Spanke-Benes [30], cross switch matrix [31] and Path Independent Loss (PILOSS) [32].…”

“…Multistage architecture with N inputs-outputs is represented in the form of a transfer matrix M with S number of stages, where each stage is represented in the form of a block diagonal matrix Ω. Each stage may consist of a straight waveguide, crossing waveguide, OSE in drop (E D s ) or through (E T s ) states [25]. Straight waveguide is represented with the value of '1' in the transfer matrix.…”

Silicon photonics has become a commonly used paradigm for on-chip interconnects to meet the requirements of higher bandwidth in computationally intensive applications for manycore processors. Design of an optical switch is a vital aspect while constructing an optical NoC topology which influences the performance of network. We present a HoneyComb optimized reconfigurable optical switch (HCROS), a 6 × 6 non-blocking optical switch where optimized reconfiguration of optical links utilizing the states of basic 2 × 2 optical switching elements (OSE) was achieved while keeping the input-output (I/O) interconnection intact. The proposed 6-port HCROS architecture was further optimized to reduce the number of OSEs to minimize overall power consumption. We proposed a generic algorithm to find the optimal switching combination of OSEs for a particular I/O link to minimize the insertion loss and power consumption. In comparison to other non-blocking architectures, a maximum of 66% reduction in OSEs was observed for the optimized HCROS, which consumes only 12 OSEs. Simulations were performed for all 720 I/O links in different configurations to evaluate the power consumption and insertion loss. We observed up to 92% power savings in the case of optimized HCROS as compared to un-optimized HCROS, and a 79% minimization in insertion loss was also reported as a result of optimization.

“…Several architectures and methods are proposed to build non-blocking optical routers/switches with minimum number of optical switching elements [16,17,18,19]. Recently, a method to reduce the number of optical switching elements by replacing them with waveguide crossings is proposed in [20]. Multiple non-blocking optical switch architectures and their topological impact on the scalability of optical switches are discussed in [21,22].…”

Optical networks on chip (ONoC) delivers a promising alternative to meet growing needs of higher bandwidth and low power consumption in manycore processors. Optical routers are the key element in ONoCs that significantly affect the performance of overall network. In this letter, we propose a rearrangeable non-blocking 6 × 6 router (RoR) constructed with 2 × 2 hybrid photonic-plasmonic switching (HPPS) elements. Router architectures with 15 HPPS elements and an optimized design using reduced HPPS elements are presented and analyzed. In optimized form, proposed design consumes only 12 HPPS elements which results in low insertion loss and crosstalk noise in comparison to the unoptimized architecture. We observe up to 50% reduction in switching elements count in comparison to other router architecture of same radix.
