WebLaser Diode. A laser diode is a semiconductor instrument identical to a light-emitting diode (LED). It uses a p-n junction to produce coherent light where all waves are at the same frequency and phase. This coherent light is emitted by a laser diode using a process “Light Amplification by Stimulated Radiation Emission,” referred to as LASER. WebPages 227 - 252. Abstract. This chapter covers the advances in organic light-emitting diode (OLED) fabrication, the process of designing and arraying different organic layers of desired thickness on a suitable substrate. The most common method of fabricating small-screen display OLEDs is by vacuum sublimation.
