title: Metal-cavity surface-emitting microlaser with hybrid metal-DBR reflectors.
abstract: We demonstrate a metal-cavity surface-emitting microlaser at room temperature using hybrid metal/distributed Bragg reflectors as well as substrate removal. Our devices operate under continuous-wave current injection at room temperature. The smallest laser is 1.0 μm in radius and ~4.0 μm in height with a circular beam shape and an output over 8 μW. The device lases at 995 nm wavelength with a threshold current of about 2.6 mA.
