Photonic-crystal surface-emitting lasers (PCSELs) have shown promise for large-area single-
mode lasers. However, the difficulty in increasing PCSEL area while preserving single-mode …

Since the initial proposal in 1999 by Noda et al., photonic crystal surface emitting lasers
(PCSELs) have shown to achieve large area, coherent lasing with a narrow, single mode …

To achieve a high-power single-transverse mode laser, we here propose a supersymmetry-
based triple-ridge waveguide semiconductor laser structure, which is composed of an …

Materials with near-zero refractive index have attracted much attention over the past decade
due to the fascinating phenomena they enabled, such as energy squeezing in thin …

It is well known that concentric diffraction gratings are capable of beaming the spontaneous
emission of large extended incoherent light sources (eg, hot radiating surfaces and …

With their compact form factor and excellent beam quality, surface-emitting lasers based on
optical bound states in the continuum (BICs) have emerged as a promising alternative to …
