“…However, a more compact, single-chip, high-power OVB generator is desired for many OVB applications. Previously, we have reported one such generator of first-order (l = 1) OVBs by integrating a SPP onto the emission surface of a photonic-crystal surface-emitting laser (PCSEL) [1]. In this paper, we report higher-order (l ≥ 1) OVBs generated by SPP-integrated PCSELs which have larger emission areas in order to achieve watt-class beam powers under electrically driven conditions.…”

“…Since then, OVB has been widely used in quantum information processing [ 3 , 4 ], quantum entanglement [ 5 ], optical micromanipulation [ 6 , 7 ], optical communication [ 8 , 9 , 10 ] and nonlinear optics [ 11 , 12 ]. Hence, with the increasing demand for practical applications, OVB needs to be further studied: from generating [ 13 , 14 , 15 ] and measuring [ 16 ] to shaping OVB [ 17 ]. Especially in recent years, shaping OVB has a research hot spot.…”

Integrating multiple independent functions into a single optical component is one of the most important topics in research on photoelectric systems. In this paper, we propose a multifunctional all-dielectric metasurface that can achieve a variety of non-diffractive beams depending on the polarization state of the incident light. Using the anisotropic TiO2 rectangular column as the unit structure, the three functions of generating polygonal Bessel vortex beams under left-handed circularly polarized incidence, Airy vortex beams under right-handed circularly polarized incidence and polygonal Airy vortex-like beams under linearly polarized incidence are realized. In addition, the number of polygonal beam sides and the position of focal plane can be adjusted. The device could facilitate further developments in scaling complex integrated optical systems and fabricating efficient multifunctional components.

“…While this design is capable of producing high-quality OAM beams in a compact area, the resonant nature of the devices limits their bandwidth and prevents multiplexing. Since then, many strategies for on-chip vortex beam generation have been demonstrated, including OAM lasers, − metasurfaces, − and analytical − and computational − grating design.…”

Vortex beams are stable solutions of Maxwell's equations that carry phase singularities and orbital angular momentum, unique properties that give rise to many applications in the basic sciences, optical communications, and quantum technologies. Scalable integration and fabrication of vortex beam emitters will allow these applications to flourish and enable new applications that are not possible with traditional optics. Here we present a general framework to generate integrated vortex beam emitters using photonic inverse design. We experimentally demonstrate the generation of vortex beams with angular momentum spanning −3ℏ to 3ℏ. We show the generality of this design procedure by designing a vortex beam multiplexer capable of exciting a custom vortex beam fiber. Finally, we produce foundry-fabricated beam emitters with wide bandwidths and high efficiencies that take advantage of multilayer heterogeneous integration.
