Abstract: An improved electromagnetic wave-emitting device is provided. A high pressure is applied to the device by potting the device in a suitable encapsulant. The potted device exhibits a decreased threshold current density and an increase in its efficiency. Additionally, the device has a more durable structure and an increased shelf life.
