Embodiment Construction

[0023] see figure 2 , the present invention provides an integrated reconfigurable optical add / drop multiplexer based on a microring resonator, including:

[0024] The transverse waveguide 10 and the vertical waveguide 20 form a vertical crossing waveguide; the transverse waveguide 10 includes an input end and a through end; the vertical waveguide 20 includes an upload end and a download end.

[0025] The first microring 30 and the second microring 40, the first microring 30 and the second microring 40 are cascaded to form a cascaded double microring structure with different radii; the resonance wavelength of the cascading double microring structure is λi , i=1, 2, ..., 16, each resonance wavelength represents a channel.

[0026] The double microring structure with different cascading radii described therein has a predetermined coupling distance with the vertical crossing waveguide formed by the transverse waveguide 10 and the vertical waveguide 20, and the predetermined coup...
