Simulative analysis of scalable and low-latent photonic switch for data center applications

Abstract Data center requirements for entertaining many users in a minimum amount of time with maximum speed are expensive and power-hungry. To overcome this problem, we present a fast, scalable, all-photonic 3-stage interferometric-loop-based interconnecting switch for data centers. A short response time of 1.33 ns is achieved by utilizing semiconductor optical amplifier (SOA)-based non-linearities, which is superlative to previously reported techniques. The high values of (Optical signal-to-noise ratio) OSNR of 20.93 dB, extinction ratio (ER) of 19.9 dB, and Q-factor of 24.5 show excellent working of implemented configuration. The structure is also evaluated for an optimized bias current of 0.15 A to achieve improved error-rate of 10 −17 . To check the stage-wise power consumption, continuous monitoring and evaluation of power per stage is done. The measurement shows performance enhancement when the high input power imposes its effect on it. The parametric comparison is performed using received power, Q-factor, and ER for 2 × 2, 4 × 4, and 8 × 8 switching interconnects. The consistency in extinction ratio shows that configuration can handle high powers and also maintain good quality of service simultaneously. The design ensures high switching accuracy and signal quality through SOA-based amplification, non-blocking architecture, and integrated 3R-regeneration for longer, high-speed transmissions. The parameter reliability with progressing stage proves that proposed structure is a good solution to scalability and latency challenges for data centers.
