[0047] The present invention will be further described below in conjunction with the drawings.
[0048] From figure 1 It can be seen that the self-locking dual optical frequency comb generating system based on the microring resonant cavity of the present invention includes two parts: the ring resonant cavity 1 generating orthogonal dual optical frequency combs and the dual optical frequency comb separating system 2. The ring resonator 1 includes an optical amplifier 11, an optical isolator 12, a first polarization controller 13, a microring resonator 14, an optical fiber splitter 15 and an optical filter 16 which are sequentially connected by a polarization maintaining fiber 17 in the cavity. The devices in the figure are connected in sequence, but there is no special requirement for the order of the front and back connections of the devices in the specific implementation process.
[0049] The dual optical frequency comb separation system 2 includes a polarization beam splitter 21 ...
