| These simulation images show how the light interference pattern interacts with the nanolaser arrays. (a) Schematic of spatial interference between TE00 and TE01 modes along the microfiber. Here, two photonic crystal nanobeam lasers (PCN1 and PCN2) are attached to the surface of the microfiber in a line. (b) Difference in effective refractive index (Δn) of TE00 and TE01 modes and corresponding half beat length (Lπ), (c) Log |E|2 profile of PCN cavity mode in the xy-plane and SEM image of fabricated InGaAsP PCN laser. (d, e) |E|2 profiles of the pump beam in the xz- and yz-planes, respectively, where the beam propagates from left to right. (f) Absorbed power density profiles along the xy-plane at the vertical center of PCNs. Credit: Korea University. |
