Principle of FP Laser Diode
A Fabry–Pérot laser diode (FP laser diode) is the most common type of laser diode, having a laser resonator which is a Fabry–Pérot interferometer. This means that substantial light reflections occur at both ends, but not within the gain medium. FP laser cavity functions as a Fabry-Perot interferometer, which is based on the fundamental principle of multiple beam. A Fabry‑Perot (FP) laser is a common, cost‑efficient light source used within optical transceiver modules, particularly SFP modules. Its primary application is in low-data-rate short-distance transmission over distances of up to 20 kilometers.

Why do laser diodes have voltage
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. As a result, when designing an adjustable power supply, one of those two parameters must be variable, and the other constant if you want to be able to tune the power supply to your desired output.
