Why are transistors not used in optical modules
Since photons inherently do not interact with each other, an optical transistor must employ an operating medium to mediate interactions. An optical transistor, also known as photonic transistor, optical switch or light valve, is a device that switches or amplifies optical signals. Electricity flowing through wires creates heat, RF interference, inefficient power usage, etc. Is there a transistor-like device, that doesn't use electricity at all; only optical signals? Why are there no optical CPUs? How about optical. An optical module is a typically hot-pluggable optical transceiver used in high-bandwidth data communications applications. Optical modules typically have an electrical interface on the side that connects to the inside of the system and an optical interface on the side that connects to the outside. A: Optocouplers are well known as optoisolators providing an isolated galvanic barrier between the input and output utilizing infrared light.

A brief introduction to laser diodes
A laser diode (LD, also injection laser diode or ILD or semiconductor laser or diode laser) is a device similar to a in which a diode pumped directly with electrical current can create conditions at the diode's. Driven by voltage, the doped p–n-transition allows for of an electron wit.

How damaging are laser diodes
Diode lasers are very reliable under normal operating conditions. However, like most semiconductor devices, they can be damaged or destroyed by inadvertent electrical or static discharges (ESD). This optical damage can happen even with a momentary over-current. Here, absorption and temperature build up in a positive feedback loop that eventually leads to material destruction. Symptoms of damage include reduced output power, threshold-current shift. One of the damage mechanisms is optically related, and occurs when the laser diode is producing light (referred to as “lasing”), and the optical energy density exceeds the laser diode's integral mirrors' reflective capacity. When this occurs, the mirrored surface permanently loses its reflectivity. Protecting a laser diode boils down to one core principle: rigorously controlling the electrical current and thermal environment at all times.
