Novel Subwavelength Grating Surface Emitting Laser

We present a new class of surface emitting lasers utilizing a single-layer high-index-contrast subwavelength grating, instead of conventional DBR. Single polarization mode emission with low threshold current and 1mW output power was obtained at 850nm wavelength. The realization of VCSELs has been significantly limited by the choice of material available for making highly reflective distributed ...

Quantum cascade surface-emitting photonic crystal laser.

We combine photonic and electronic band structure engineering to create a surface-emitting quantum cascade microcavity laser. A high-index contrast two-dimensional photonic crystal is used to form a micro-resonator that simultaneously provides feedback for laser action and diffracts light vertically from the surface of the semiconductor surface. A top metallic contact allows electrical current ...

Vertical cavity surface emitting terahertz laser.

Vertical cavity surface emitting terahertz lasers can be realized in conventional semiconductor microcavities with embedded quantum wells in the strong coupling regime. The cavity is to be pumped optically at half the frequency of the 2p exciton state. Once a threshold population of 2p excitons is achieved, a stimulated terahertz transition populates the lower exciton-polariton branch, and the ...
