can anyone plz teach me how to interface a LASER diode with microcontroller . The LASER diode will be used to transmit the output data(in binary format)of microcontroller using an optical fiber .... plz reply asap .... thanx for reading this and for your help .....
Ignore that it is a LASER (by the way, even if "LASER" might stand for Light Amplification by Stimulated Emission of Radiation, the word "laser" has been added to the dictionary since quite a number of years), and instead concentrate on what it requires.
What is the expected voltage? What current? What transfer rate, i.e. how quickly must you be able to turn on/off the drive? A very important thing here is if it has a digital signal intended to modulate it, or if it is a raw LED diode where you are responsible for the exact drive current, or if you are going to turn on/off a power-converter that will produce the specific drive current.
... and understand what your microcontroller can provide.
Marrying the two is the essence of Interfacing anything to anything else: www.8052.com/.../160143
