A waveguide device and a chip comprising same. The waveguide device comprises a first waveguide structure (150, 250, 350) and a second waveguide structure (160, 260, 360) which are coupled. The first waveguide structure (150, 250, 350) is constituted by a first straight waveguide (110, 210, 310), a first bent waveguide (101, 201, 301) and a second straight waveguide (120, 220, 320), and the first straight waveguide (110, 210, 310) and the second straight waveguide (120, 220, 320) are connected via the first bent waveguide (101, 201, 301). The second waveguide structure (160, 260, 360) is constituted by a third straight waveguide (130, 230, 330), a second bent waveguide (102, 202, 302) and a fourth straight waveguide (140, 240, 340), and the third straight waveguide (130, 230, 330) and the fourth straight waveguide (140, 240, 340) are connected via the second bent waveguide (102, 202, 302). The waveguide device avoids the mutation of the spatial structure of the device resulting from the direct crossing of the waveguides, thus reducing the transmission loss effectively when the light beam is transmitting. |
