A Simple Method to Build High Power PCSEL Array with Isolation Pattern Design
Crystals, 2022 Photonic crystal surface-emitting lasers (PCSELs) hold promising properties of both edge emitting lasers (EELs) and vertical-cavity surface-emitting lasers (VCSELs). They possess high output power while radiating light vertically, being thought of as the

Large mode-volume, large beta, photonic crystal laser resonator
AIP Advances, 2014 We propose an optical resonator formed from the coupling of 13, L2 defects in a triangular-lattice photonic crystal slab. Using a tight-binding formalism, we optimized the coupled-defect cavity design to obtain a resonator with predicted single-mode ...

Vertical-Cavity Surface-Emitting Laser With a Chiral Nematic Liquid Crystal Overlay
IEEE Photonics Journal, 2014 We demonstrate measurement results of the light emission of vertical-cavity surface-emitting lasers (VCSELs) with chiral liquid crystal (CLC) overlay (CLC-VCSEL). Two different CLC materials with different chiral-phase temperature range are presented and

Inverse-cavity structure for low-threshold miniature lasers
Scientific Reports, 2022 Creating micro and nano lasers, high threshold gain is an inherent problem that have critically restricted their great technological potentials. Here, we propose an inverse-cavity laser structure where its threshold gain in the shortest-cavity regime is ...
