Photonics Lab Report :: Photonic Photons

Photonics LabIntroductionIn the world of communication, lasers can be very helpful in transporting a variety of information across the planet. In this experiment, we decided to advance our knowledge ab come on lasers and perform more tedious activities with them. Instead of shooting lasers finished a gelatin substance and reading angles in which they reflect, we were going to mistreat it up a bit. This time our final goal was to be suitable to verbally communicate through space victimization a laser. Photonics is depict as science and technology based on and concerned with the hightail it of electrons. The Communication system that relies on the flow of depictionns is known as a Photonic Link. I plan to successfully be able to communicate oer free space using a photonic link in the bar of this experiment.Materials/MethodsIn this experiment, we needed the following materials A Laser (with all hook-ups) A suggest origin 2 Amplifier circuits A photo-detector An Oscilloscope ( with hook-up cables) A loud speaker system system Soldering Iron for putting together circuits TransformerTask 1 seduce one of the Amplifier circuits following directions and using the soldering iron. plug into battery and speaker to the circuit. attribute the amplifier circuit to the oscilloscope and signal generator. consort the signal generator directly to the oscilloscope. encrypt the voltage amplitude from the amplifier from the minimum and maximum settings. Calculate the gain in decibels.Task 2Modulate the laser using the transformer. Turn on amplifier circuit. Point laser towards the photo resistor. Connect to the oscilloscope. get hold the amplifier until you can hear the signal generator signal.Task 3Connect oscilloscope to amplifier. Modulate laser as before. Point laser towards photo detector. Perform measurements of voltage output for different frequencies. Takemeasurements at the highest frequency that will provide a measurable voltage. Report data in a graph. Cal culate the bandwidth of the voltages that were measured.Task 4Construct the second amplifier circuit. Connect a microphone to the amplifier instead of a photo detector. Connect the transformer to the amplifier. Connect voltage supply to the laser. Adjust the amplifiers until you can successfully project your piece through space using the laser and it can come out the speaker on the other circuit.ResultsIn the first task we were able to successfully solder together the circuit and it was able to amplify the signal from the generator, as it should. In the second task, we were able to modulate the laser. In the threesome task we were able to calculate the bandwidth and we received the following information potency Vs.
