摘要	Implementation of multifunctional optical elements by controlling spectrum and wavefront simultaneously with conventional approaches is a difficult task due to their complicated structures and fabrication processes. We present a method to construct multifunctional optical components to achieve independent function at every operating wavelength in a shared-aperture configuration. The component contains amounts of periodical interleaved sectors composed of a metasurface layer sandwiched by two distributed Bragg reflectors (DBRs) and another metasurface layer upon the former. To demonstrate this method, we design and simulate a component which can focus the light wave at 0.521 mu m on a spot and deflect the wave at 0.585 mu m to a desired angle. The realized functions for different wavelengths will not interfere with each other, showing a low-crosstalk characteristic. Further improvement is applied to reduce the diffraction effect for light focusing and deflecting with smaller sidelobes by replacing the fixed period of the interleaved sectors with random periods. This work may provide an effective way of controlling the multiwavelength electromagnetic waves in extensive integrated optical systems.
