Photonics Lab Report :: Photonic Photons

Photonics LabIntroductionIn the world of communication, lasers discount be very helpful in transporting a variety of education across the aimet. In this experiment, we decided to advance our knowledge about lasers and fulfil more tedious activities with them. Instead of shooting lasers through a jelly substance and reading angles in which they reflect, we were going to step it up a bit. This time our final goal was to be adequate to verbally transfer through pose using a laser. Photonics is described as knowledge and technology based on and concerned with the flow of electrons. The Communication clay that relies on the flow of photons is known as a Photonic Link. I plan to successfully be able to communicate over free aloofness using a photonic link in the end of this experiment.Materials/MethodsIn this experiment, we inevitable the next materials A Laser (with all hook-ups) A signal root 2 Amplifier moves A photo-detector An Oscilloscope (with hook-up cables) A speake r Soldering campaign for putting together circuits TransformerTask 1Construct one of the Amplifier circuits following directions and using the conjoining iron. Connect battery and speaker to the circuit. Connect the amplifier circuit to the oscilloscope and signal generator. Connect the signal generator directly to the oscilloscope. portend the electric potential amplitude from the amplifier from the minimum and maximum settings. cast the gain in decibels.Task 2 influence the laser using the transformer. Turn on amplifier circuit. Point laser towards the photo resistor. Connect to the oscilloscope. Adjust the amplifier until you can try 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 deliver a measurable voltage. Report data in a graph. Calculate the bandwidth of the voltages th at were measured.Task 4Construct the second amplifier circuit. Connect a mike to the amplifier instead of a photo detector. Connect the transformer to the amplifier. Connect voltage add up to the laser. Adjust the amplifiers until you can successfully project your voice 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 third task we were able to calculate the bandwidth and we received the following information Voltage Vs.
