摘要： A tapered waveguide includes a central waveguide (10) and shallow-etched strip waveguides (20) disposed on both sides of the central waveguide. Each shallow-etched strip waveguide (20) is of a structure with a gradually changing width, and an outline, away from the central waveguide (10) and in a length direction, of the shallow-etched strip waveguide (20) is a concave arc without an abrupt change. An effective refractive index changes slowly and an insertion loss of a device can be effectively reduced. In addition, a wider area of the shallow-etched strip waveguide has a shorter length. In this way, a length of the device is effectively reduced, thereby facilitating miniaturization of the device. A silicon-based chip is further disclosed.

By means of the optical interconnector (915), the optical signal having the first resonant wavelength in the first optical waveguide (102) can be coupled to the second optical waveguide (103) after passing through the first vertical coupled cavity (100). In this way, the optical interconnector (915) can be used to implement optical signal sharing between different layers.
