“…Moving forward, the vectorial nature of mini-BICs could be exploited to build chip-scale lasers capable of emitting coherent structured light for high-capacity optical communication (46) and high-dimension quantum information processing (47). It is also highly desirable to implement the electrical injections in active BIC devices, as successfully demonstrated for suspended PhC defect lasers (48) and on-substrate surface emitting laser with less thermal effect (49,50). From the perspective of applications, the realization of mini-BIC laser may immediately boost the development of on-chip cavity QED (51) and the integrated nonlinear photonics (52) in which high-Q factors and small mode volumes are highly beneficial.…”

The pursuit of compact lasers with low thresholds has imposed strict requirements on tight light confinements with minimized radiation losses. Bound states in the continuum (BICs) have been recently demonstrated as an effective mechanism to trap light. However, most reported BIC lasers are still bulky due to the absence of in-plane light confinement. Here, we combine BICs and photonic bandgaps to realize three-dimensional light confinements, as referred to miniaturized BICs (mini-BICs). We demonstrate highly compact active mini-BIC resonators with a record high-quality ( Q ) factor of up to 32,500, which enables single-mode lasing with the lowest threshold of 80 W/cm 2 among the reported BIC lasers. In addition, photon statistics measurements further confirm the occurrence of the stimulated emission in our devices. Our work reveals a path toward compact BIC lasers with ultralow power consumption and potentially boosts the applications in cavity quantum electrodynamics, nonlinear optics, and integrated photonics.

The pursuit of compact lasers with low-thresholds has imposed strict requirements on tight light confinements with minimized radiation losses. Bound states in the continuum (BICs) have been recently demonstrated as an effective mechanism to trap light along the out-of-plane direction, paving the way to low-threshold lasers. To date, most reported BIC lasers are still bulky due to the absence of in-plane light confinement. In this work, we combine BICs and photonic band gaps to realize three-dimensional (3D) light confinements, as referred to miniaturized (mini-) BICs. Together with 3D carrier confinements provided by quantum dots (QDs) as optical gain materials, we have realized highly-compact active BIC resonators with a record-high quality (Q) factor up to 32500, which enables single-mode continuous wave (CW) lasing with the lowest threshold of 80 W/cm 2 among the reported BIC lasers. In addidtion, our photon statistics measurements under both CW and pulsed excitations confirm the occurence of the phase transition from spontaneous emission to stimulated emission, further suggesting that conventional criteria of input-output and linewidth are not sufficient for claiming nanoscale lasing. Our work reveal a via path towards compact BIC lasers with ultra-low power consumption and potentially boost the applications in cavity quantum electrodynamics (QEDs), nonlinear optics and integrated photonics.

“…Photonic crystal surface emitting laser (PCSEL) architecture can enhance brightness of semiconductor lasers. Monolithic epitaxially regrown PCSEL based on nitride, arsenide, and phosphide diode laser technologies operating in visible and near infrared telecom region of spectrum have been demonstrated [1,2,3]. The extension of the PCSEL technology to longer wavelength range above 4 µm was accomplished using quantum cascade laser design [4].…”

We report on the continuous wave (CW) room temperature operation of epitaxially regrown monolithic GaSb-based photonic crystal surface emitting diode lasers (PCSEL) with ≈ λ 2 µm. The devices are based on laser heterostructure containing carrier stopper layer designed to inhibit electron leakage into buried photonic-crystal section. Atomic hydrogen cleaning of the nanopatterned surface followed by optimized epitaxial step resulted in highly uniform air-pocket-retaining regrowth. The increase of the number of air-pockets in unit cells of the buried photonic crystal layer led to enhancement of the PCSEL output power and improvement of the far field pattern The PCSELs with buried high-index-contrast photonic crystal utilizing four air-pockets per unit cell generated 30 mW of continuous wave power from 200 µm diameter aperture.
