Surface-emitting semiconductor lasers represent a class of devices in which the optical emission is perpendicular to the semiconductor wafer. This design contrasts with conventional edge-emitting ...

Light-emitting diodes (LEDs) also emit light perpendicular to the chip surface, but emissions spread out laterally for a more diffuse beam. Edge-emitting lasers (EELs) are available in two common ...

Abstract: High performance edge-emitting microlasers with deeply etched distributed Bragg reflectors (DBRs) were fabricated on an AlGaAs-GaAs laser structure with a single GaInAs quantum dot (QD) ...

The vertical-cavity surface-emitting laser (VCSEL) is emerging as a key element for next-generation information processing systems and technologies. This laser has the ease of manufacture of the light ...

BofA analyst favors 5 SMid cap names in semiconductor sector for strong growth, EPS leverage, and TAM expansion, raises price ...

The newly developed device is a vertical-cavity surface-emitting laser (VCSEL) that operates at 1,550 nanometers—the standard wavelength used in long-distance optical fiber networks. Until now, VCSELs ...

This paper introduces an innovative approach to enhancing surface emission in terahertz quantum cascade lasers (THz QCLs) by incorporating a plasma-assisted layer into photonic crystal waveguides.
