“…Lasing action can naturally occur at BIC states where the quality factor diverges. The angular (wave vector) tunability of the BICs makes them great candidates for onchip beam steering [40]. Furthermore, photonic crystal lasers through BICs are naturally vector beams [41,42,43], which are important for particle accelerations, optical trapping, and stimulated emission depletion microscopy.…”

Optical bound states in the continuum (BICs) have recently been realized in photonic crystal slabs, where the disappearance of out-of-plane radiation turns leaky resonances into guided modes with infinite lifetimes. We show that such BICs are vortex centers in the polarization directions of far-field radiation. They carry conserved and quantized topological charges, defined by the winding number of the polarization vectors, which ensure their robust existence and govern their generation, evolution, and annihilation. Our findings connect robust BICs in photonics to a wide range of topological physical phenomena.

“…It is noted that one way to steer light by a magnetic field was proposed based on photonic hall effect [13]. Recently, a series of important progress has been made toward the on-chip beam steering, including the use of the photonic crystal [14], nano Yagi-Uda antenna [15] and flat dielectric gratings [16]. Due to the ultra-compact characteristic and the extremely low absorption loss feature in the dielectric system, our structure may provide yet an alternative approach to gain high degree of on-chip control over the flow of optical beams for optical circuit.…”

“…However, they are bulky and their beam-steering speed is limited because of their moving parts. Various approaches for non-mechanical beam steering have been reported, 65,66) which include an optical phased array, a liquid crystal phase modulator, an electro-optic crystal deflector, an in-plane laser array, a photonic crystal laser, a phase-locked VCSEL and so on.…”

A vertical cavity surface emitting laser (VCSEL) was born in Japan. The 37 years' research and developments opened up various applications including datacom, sensors, optical interconnects, spectroscopy, optical storages, printers, laser displays, laser radar, atomic clock and high power sources. A lot of unique features have been already proven, such as low power consumption, a wafer level testing and so on. The market of VCSELs has been growing up rapidly and they are now key devices in local area networks based on multi-mode optical fibers. Optical interconnections in data centers and supercomputers are attracting much interest. In this paper, the advances on VCSEL photonics will be reviewed. We present the high-speed modulation of VCSELs based on a coupled cavity structure. For further increase in transmission capacity per fiber, the wavelength engineering of VCSEL arrays is discussed, which includes the wavelength stabilization and wavelength tuning based on a micro-machined cantilever structure. We also address a lateral integration platform and new functions, including high-resolution beam scanner, vortex beam creation and large-port free space wavelength selective switch with a Bragg reflector waveguide.
