Orbital angular momentum is a fundamental degree of freedom of light that manifests itself even at the single photon level. The coherent generation and beaming of structured light usually requires bulky and slow components. Using wave singularities known as bound states in continuum, we report an integrated device that simultaneously generates and beams powerful coherent beams carrying orbital angular momentum. The device brings unprecedented opportunities in the manipulation of micro-particles…

Ultralow-threshold laser using super-bound states in the continuum

The concept of a supercavity mode created by merging symmetry-protected and accidental bound states in the continuum in the momentum space is employed, and an efficient laser based on a finite-size cavity with a small footprint is realized.

Generating optical vortex beams by momentum-space polarization vortices centred at bound states in the continuum

Optical vortices, beams with spiral wavefronts and screw phase dislocations, have been attracting increasing interest in various fields. Here, we theoretically propose and experimentally realize an

Bound States in the Continuum in Fiber Bragg Gratings

Optical fibers typically confine light through total internal reflection or through photonic bandgaps. Here we show that light can be perfectly guided in optical fibers through a different mechanism

Bound states in the continuum in low-contrast fiber Bragg gratings

In typical waveguides and optical fibers, light is confined through total internal reflection or through photonic bandgaps. Bound states in the continuum (BICs) confine light through destructive

High-Q resonance in GeSn-based bound states in the continuum microcavity.

A novel design that takes advantages of both the direct bandgap dielectric material GeSn and the BIC phenomenon is proposed that can emit light at the wavelength of 1870 nm with higher luminous intensity and improve the emission process.

Ultra-low threshold continuous-wave quantum dot mini-BIC lasers

Highly compact lasers with ultra-low threshold and single-mode continuous wave (CW) operation have been a long sought-after component for photonic integrated circuits (PICs). Photonic bound states in

Optical response induced by bound states in the continuum in arrays of dielectric spheres

We consider an optical response induced by bound states in the continuum (BICs) in arrays of dielectric spheres. By combining the quasi-mode expansion technique with coupled mode theory (CMT), we put

Photonic Bound States in the Continuum in Si Structures with the Self‐Assembled Ge Nanoislands

Germanium self‐assembled nanoislands and quantum dots are very prospective for CMOS‐compatible optoelectronic integrated circuits but their photoluminescence (PL) intensity is still insufficient for

Monolayer Excitonic Emission for Imaging Spatial Dispersion of Photonic Crystals

Spatial dispersion of a photonic crystal manifests itself as an angle dependent optical response. Here, we use the emerging two-dimensional transition metal dichalcogenides (TMDCs) as a photon sour...



Orbital angular momentum microlaser

A microring laser is demonstrated producing a single-mode OAM vortex lasing with the ability to precisely define the topological charge of the OAM mode, which could find applications in the next generation of integrated optoelectronic devices for optical communications in both quantum and classical regimes.

Topological nature of optical bound states in the continuum.

This work shows that robust BICs in photonics are vortex centers in the polarization directions of far-field radiation, defined by the winding number of the polarization vectors, which ensure their robust existence and govern their generation, evolution, and annihilation.

Observation of trapped light within the radiation continuum

It is predicted and shown experimentally that light can be perfectly confined in a patterned dielectric slab, even though outgoing waves are allowed in the surrounding medium.

Integrated Compact Optical Vortex Beam Emitters

Silicon-integrated optical vortex emitters are demonstrated, using angular gratings to extract light confined in whispering gallery modes with high OAM into free-space beams with well-controlled amounts of OAM, confirming the theoretical prediction that the emitted beams carry exactly defined and adjustable OAM.

Experimental observation of optical bound states in the continuum.

These experiments demonstrate ideas initially proposed by von Neumann and Wigner in 1929 and offer new possibilities for integrated optical elements and analogous realizations with cold atoms and optical trapping of particles.

A new method for free-space optical communication, where the transmitter encodes data into a composite computer-generated hologram and the receiver decodes through a retrieved array of sidelobe-modulated optical vortices (SMOVs), which possesses the ability to greatly increase the capacity of data transmission.

The bound states in the continuum demonstrate a giant Poynting vector spiraling around the array and can be excited by a plane wave with incident linear polarization with a small tilt relative to the axis of the array.

We demonstrate controlled rotation of optically trapped objects in a spiral interference pattern. This pattern is generated by interfering an annular shaped laser beam with a reference beam. Objects
