Broadband Routing in a 1$\,\times\,$4 SOI Switch Array Using Fifth-Order Resonant Elements

We present broadband data routing in a 1×4 multiport switch with fifth-order resonant elements. A 3-dB bandwidth of >;100 GHz is measured with an off-state signal extinction exceeding -25 dB on all paths. A wavelength misalignment tolerance between 10-Gb/s signal wavelength and the resonant wavelength of the switch element is presented. Low-power penalty routing is achievable for signal detuning at up to ±50 GHz.
