ABSTRACT The study aims to propose that Free-space Optical (FSO) Communication can be used in consumer level electronics, where ordinary people can benefit and enjoy the advantage of this technology with low-cost laser communication link. To demonstrate this, a program was created that acts as a "Messaging App" using a transceiver that consists of lasers, photodiodes, and the Arduino Uno. The basic concept of this is when the transceiver sends data (message) through a Graphical User Interface (GUI) and then transmitted through a laser beam directed towards the sensor of the other device. The decoding process on this device (receiving end) allows displaying of the message sent in its GUI.

INTRODUCTION Free-space Optical (FSO) Communication is the wireless transmission of data using a technology that uses light propagating in free space. FSO systems require no expensive and laborious installations, and there are no security upgrades necessary. Regarding with the power consumption, this technology uses low power in transmitting data. Dissimilar to the radio and microwave system, FSO system does not require spectrum license or frequency coordination among its users.

Research Questions This study aimed to prove that the free-space photonic technology can be used in communication technology in an inexpensive cost and aims to answer the following questions: 1. 2. 3. 4.
Is it possible to transmit and receive data through laser? How feasible the project is? How efficient the project is? Is it marketable?

Conceptual Framework
The block diagram shows the transmission and reception of data through a LASER channel. The end user types a text message on the User Interface created from Visual Basic. The program itself converts the input message into a stream of data, the microcontroller converts the stream of data into pulse width modulated signal. The LASER pulses are received by a photo transistor. Through a reverse process, these received pulses are converted back to stream of data. Finally, these stream of data, with the help of Visual Basic program (the same program used by the transmitting user), are converted back into a text message. Basically, creating an interface or a messaging application using Laser as its medium of communication. 3/22/2019

Procedure and Computational Details The procedure serves the primary purpose of furthering research on LASER Communications and how its conditions and specifications can be utilized and develop to carry out data transmission in a consumer-level product. Hence, the first step that should be taken is to gather much all the useful references and article materials that will properly correlate with the study.

DISCUSSION According to the results of the data analysis, the system has shown a high efficiency rating in terms of message reception within a reasonable range and a fair speed in terms of transmission and reception. After reviewing related researches and simulating our devices through several tests and trials, we have successfully proven and created the possibility of building an FSO communication system suitable for digital instant messaging with an inexpensive circuitry design. The effort of building a design that is a low-cost yet efficient system has been reflected through analyzing the overall performance of the actual device based on the parameters.
