Abstract: A wavelength selective switch includes a first optical switching engine. The optical switching engine is configured to deflect a transmission direction of a first light sub-beam along a port direction to send a deflected first light sub-beam to a first reflector, and to deflect a transmission direction of a second light sub-beam along the port direction to send a deflected second light sub-beam to a second reflector. The first reflector reflects the deflected first light sub-beam along a dispersion direction to send a reflected first light sub-beam to a first area of a second optical switching engine. The second reflector reflects the deflected second light sub-beam along the dispersion direction to send a reflected second light sub-beam to a second area of the second optical switching engine.
