Embodiment Construction
[0031] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.
[0032] Such as figure 1 As shown, this example provides a non-magnetic photonic crystal non-reciprocal dual-channel narrowband filter, including a vertical input main waveguide (waveguide 1 in the figure), two horizontal output waveguides (waveguide 2 and waveguide 3 in the figure) , a microcavity; the microcavity includes a dielectric column inside the microcavity and a dielectric column outside the microcavity (M in the figure is a dielectric column outside the microcavity).
[0033] The filter in this embodiment only destroys the structural symmetry of the photonic crystal, and realizes the optical non-reciprocal transmission function by using whether the modes match when the waveguide and t...
