The voltage appears across the laser diode as a result of the current flowing through it. Stimulated emission can be produced when. The optical power value, Po, is the most basic characteristic of a laser diode. This parameter is defined as the light output intensity in the case that a specific current is applied to the device in the forward direction, and is typically expressed in units of W. A PIN diode (see Figure 1 below) is a diode with a wide, undoped intrinsic semiconductor region sandwiched between a p -type semiconductor and an n -type semiconductor. Both the p -type and n -type regions are typically heavily doped.
