Improvements in and relating to Photonics An optical switch for receiving an optical signal from an optical signal source and for outputting the optical signal comprises an optical router configured for routing the optical signal conditional on the detection of a single photon. The optical router comprises and optical resonator, a first optical pathway part comprising the optical resonator, and a second optical pathway part. An optical input coupling part receives the optical signal for coupling the received optical signal into the first optical pathway part and into the second optical pathway part. An optical modulator coupled to a single-photon detector unit outputs a detection signal in response to the detection of a single photon. The optical modulator is configured, in response to the detection signal, to modulate the refractive index of the optical resonator to change an optical phase shift incurred by the optical signal upon passage through the optical resonator such that an optical interference results in a routing of the output optical signal to one of the first and second optical pathway parts selected conditional on the detection of a single photon.

This application belongs to the field of on-chip optical communication, specifically disclosing a fully connected reconfigurable optical router. This application proposes four tunable microring units with different adjustable optical paths. A first joint structure consisting of a first tunable microring unit – a fourth tunable microring unit – a third tunable microring unit – a second tunable microring unit located in the first row, and a second joint structure consisting of a fourth tunable microring unit – a second tunable microring unit – a first tunable microring unit – a third tunable microring unit located in the second row, are combined using a shared waveguide structure and a reconfigurable microring array design. This allows each port to function as either an input or output in different configurations, with the port role dynamically determined by the microring state. This achieves full port connectivity, overcoming the routing limitations of existing fixed input / output ports. This full connectivity mechanism significantly improves port flexibility, giving the system greater freedom in path arrangement, scheduling, and topology expansion.

The invention discloses a bandwidth-controllable topological optical filter without an external magnetic field. According to the device, air, isotropic media and topological continuous media are in direct contact to form a topological optical filter which does not need an external magnetic field and is controllable in bandwidth. The topological continuous medium has a chiral surface state in the same transmission direction in the air and at the boundary of the isotropic medium. By introducing a plurality of structural defects, the scattering suppression transmission characteristic of the surface wave can be tested. By changing the relative dielectric constant epsilon of isotropic media in the topological optical filter, the topological optical filter with adjustable bandwidth and scattering suppression can be realized. The method is suitable for bandwidth-adjustable topological devices such as topological optical filters, topological optical isolators, topological optical waveguides and topological optical routers, and higher flexibility is provided for designing bandwidth-adjustable multi-channel topological photonic devices without additional magnetic fields.
