Laser Communication, Laser Diode,LM386 IC, Reception, Solar panel, Transmission.


This paper aims at transmitting data via. a medium (air), using a Laser Diode. The reception is accomplished by using a Solar panel. On both the sites of transmission and reception, LM386 ICs are used for amplification and modulation. The input is taken from a ‘.mp3’ supported device, via. a 3.5mm jack (In this case a smartphone). The input taken is amplified and transmitted using a Laser diode and the beam is directed onto a Solar Panel. The solar panel and the reception system vary the intensity levels as required and eventually, the music is played out loud by the loudspeaker.
