Vertically Emitting Microdisk Lasers
Publié en 2008
We describe the modeling of microdisk lasers displaying vertical emission. The devices are THz quantum cascade lasers with metallic gratings fabricated along the circumference. The emission properties of the fabricated devices are well explained by the model, good mode control is obtained, and the collected power from a patterned device is increased 50 times with respect to unpatterned devices.
