Orbital angular momentum beams with helical wavefronts provide additional degrees of freedom for modern optics and provide emerging resources for classical and quantum information technology. The eigenstates of photon's orbital angular momentum form a complete set of orthogonal basis vectors, and are ideal carriers for high-dimensional quantum information. The large-scale application of orbital angular momentum beyond the principle demonstration urgently requires to develop photonic integrated devices capable of transmitting, generating, manipulating, and processing orbital angular momentum. At present, we can faithfully transmit and generate orbital angular momentum on photonic integrated chips, and increase the degrees of freedom and resources on integrated chips, which will greatly promote the development of integrated and scalable quantum computing and quantum simulation.
