Abstract
A rare earth-doped solid-state integrated laser which includes an optical waveguide, and a laser cavity including at least one subwavelength mirror. The subwavelength mirror is disposed in or on the optical waveguide. The optical waveguide portion within the laser cavity includes active media comprising both a rare earth and semiconducting atoms or compounds. A structure for pumping the semiconducting semiconducting atoms or compounds is provided, such as electrodes sandwiching the active media wherein the semiconducting atoms or compounds transfer energy obtained from the pumping to the rare earth, thus permitting the laser to laze.
