摘要： An adjustable wide-spectrum wavelength-insensitive directional coupler, comprising a substrate (100). A first-stage directional coupling structure (1), a phase-shifting structure (2), and a second-stage directional coupling structure (3) are sequentially connected and disposed on the substrate (100). The phase-shifting structure (2) comprises a phase-shifting curved waveguide, a phase-shifting straight waveguide (22), and a third modulation component (26), wherein the third modulation component (26) is disposed on the phase-shifting curved waveguide. One end of the phase-shifting curved waveguide is connected to an output end of a directional coupled waveguide I (16) of the first-stage directional coupling structure (1), and the other end of the phase-shifting curved waveguide is connected to an input end of a directional coupled waveguide III (30) of the second-stage directional coupling structure (3). One end of the phase-shifting straight waveguide (22) is connected to an output end of a directional coupled waveguide II (17) of the first-stage directional coupling structure (1), and the other end of the phase-shifting straight waveguide (22) is connected to an input end of a directional coupled waveguide IV (31) of the second-stage directional coupling structure (3). The adjustable wide-spectrum wavelength-insensitive directional coupler achieves wide-spectrum wavelength-insensitivity, a wide spectrum of splitting-ratio adjustment and low loss, and is of a compact size for easy integration with other devices.
