Wafer Bonded Subwavelength Metallo-Dielectric Laser

Light sources that are compatible with the silicon photonics platform are the key elements needed for photonic integrated circuits on silicon. Here, we report optically pumped wafer bonded metallodielectric lasers, subwavelength in all three dimensions (250-nm gain core radius) operating at 77 K, as well as near-subwavelength (450-nm gain core radius) operating at room temperature.
