All-optical switches are among the most important parts of integrated photonics. Ultrahigh speed and ultralow energy consumption two necessary indexes all-optical switches. Traditionally, based on concepts such as micro-ring resonators, surface plasmon polaritons, photonic crystals, metamaterials. However, platforms cannot satisfy demand for high performance To overcome limited response time co...

The ultrafast response and broadband absorption of all-optical graphene switches are highly desirable features for on-chip photonic switching. However, because is an atomically thin material, its guided optical modes relatively low, resulting in high saturation thresholds switching energies these devices. To boost the graphene, we present a practical design electrically-biased switch that integ...

Optical switches are necessary for achieving reliable, fast and flexible modular communication means in future systems. Free space approaches are advantageous since they fully use the two dimensions optics offer. A folded architecture based on a polarization code is proposed for optical switching. The suggested system is compact and appropriate for both intraand intercomputer communication. The...
