The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.
Referring to fig. 1, the present invention provides a four-port optical-electrical router based on surface plasmon resonators, which includes five rectangular MOS resonators, four straight-through optical waveguides, four input ports, and four output ports. In fig. 1, the small circles (i-v) represent 5 MOS resonators, the numbers (1-4) represent 4 input ports, the numbers (1 '-4') represent 4 output ports, the solid lines represent waveguides, and the arrowed lines → represent the signal transmission directions.
The first end input port 1 to the second end output port 2' are first optical waveguides; the second optical waveguide is arranged from the second end input port 2 to the first end output port 1'; a third optical waveguide is arranged from the third input port 3 to the fourth output port 4'; a fourth optical waveguide is arranged from the fourth input port 4 to the third output port 3';
the first end input port 1 of the first optical waveguide is coupled with the third output port 3' of the fourth optical waveguide through a first resonator; the first end input port 1 of the first optical waveguide is coupled with the fourth output port 4' of the third optical waveguide through a second resonator;
the second end input port 2 of the second optical waveguide is coupled with a third output port 3' of a fourth optical waveguide through a third resonator; the second end input port 2 of the second optical waveguide is coupled with a fourth output port 4' of the third optical waveguide through a fourth resonator;
a third end input port 3 of the third optical waveguide is coupled with a first output port 1' of the second optical waveguide through a fifth resonator; a third end input port 3 of the third optical waveguide is coupled with a second output port 2' of the first optical waveguide through a second resonator;
a fourth input port 4 of the fourth optical waveguide is coupled with a second output port 2' of the first optical waveguide through a first resonator; the fourth input port 4 of the fourth optical waveguide is coupled to the first output port 1' of the second optical waveguide via a third resonator. The four optical waveguides are straight-through optical waveguides, the five resonators are rectangular MOS resonators and are also called MOS waveguide belts, and compared with an MRR, the MOS waveguide belts are rectangular, so that the process is simple, and the precision is well controlled. The rectangular MOS resonator comprises a metal layer, an oxide layer and a semiconductor layer which are sequentially arranged from top to bottom, wherein the oxide layer is made of indium tin oxide. The resonance wavelengths of the five resonators are all equal, and the resonators have the same area and structure and the same effective refractive index. Applying a bias voltage V between metal-oxide layers in a MOS waveguide stripbias(0V＜Vbias< 3V). At the moment, the ITO layer in the MOS waveguide band is in a metal state and has a reflection effect on optical signals, so that the signals can be blocked in the original waveguide tube, the signals are directly transmitted along the current waveguide tube,as shown in fig. 2; when the bias voltage V isbiasAt 0V, the ITO layer behaves as a dielectric and resonates with a signal of a particular frequency in the original waveguide, thereby causing the signal to be transmitted across the waveguide strip into another waveguide, as shown in fig. 3. As shown in FIG. 2, when a bias voltage V is applied between the metal and oxide layers in the MOS waveguide bandbiasWhen a signal is input from an input end and passes through an MOS waveguide band, the MOS waveguide band presents a metal state due to the addition of bias voltage, so that the signal has a reflection effect, the signal is blocked in an original waveguide tube and then is output from an output end, and the state of the MOS resonator is defined as 'blocked'. As shown in fig. 3, when the bias voltage V of the MOS waveguide strip is appliedbiasWhen the signal passes through the MOS waveguide band, the signal resonates with the signal, so that the signal can enter one waveguide tube from the other waveguide tube through the MOS waveguide band and be output from the output end of the other waveguide tube, and this state of the MOS resonator is defined as "on". The optical waveguide controls the dynamic configuration of the routing signal through the bias voltage, so that the switching of the switch state is realized.

The situation when signals enter from different ports at this time is as follows: first-end input port 1 → third-end output port 3 ', second-end input port 2 → fourth-end output port 4', third-end input port 3 → first-end output port 1 ', fourth-end input port 4 → third-end output port 3'.

The first resonator is shared by the two links of the fourth input port 4 → the second output port 2 'and the first input port 1 → the third output port 3' without causing interference. Because the state switch of syntonizer needs external voltage or thermal modulation, two same syntonizers of link sharing can reduce the consumption, the utility model discloses five syntonizers have been used for the first time and have been accomplished the non-blocking route exchange of four ports.
The correspondence of each link to the resonator is given below (table 1), with the waveguide indicating that the optical signal does not pass through the resonator switch, but passes directly along the waveguide.
