LASER circuit for transmitting voice

The schematic below shows Laser circuit that can be used for transmitting voice signal. Proteus Professional 8 was used for simulation demonstration of modulating a laser with audio signal.

Fig: Laser Circuit Schematic for Audio Modulation

The audio signal is applied to the pin 5 of the LM555 timer and this varying signal modulates the LED(Laser) which is connected Pin 4 and 3 as shown. The circuit is supplied with 12V battery and the switch puts on/off the circuit operation. The resistors and capacitor forms the bias circuit and coupling capacitors.

The audio signal is a real voice signal in .wav format and applied to the circuit using the audio generator part available in the generator palette.The following figure shows how the configuration looks like-

Fig: Audio Generator Configuration

When the simulation is run we can see the LED(laser) blinking and producing blue light in accordance to the input audio signal. This is shown below-

AM modulation using diode

The schematic below shows a simple AM modulation realization circuit

Fig: AM Modulation schematic

In the schematic above, we apply message signal and a carrier signal to a diode and the output is passed through a tuned LC circuit. The message signal has frequency of 1k and the carrier signal has a frequency of 1MHz. The signal are mixed and fed into the diode(D1N4148) which performs the non-linear modulation. The output is a rectified version of the input signal. This is then mixed with the LC tuned circuit which is resonant also at 1MHz i.e. the carrier signal frequency. At the output we get a Amplitude Modulated signal.

The frequency of oscillation of the tuned circuit is given by-

\[f=\frac{1}{2\pi\sqrt{LC}}\]
 with f = 1MHz and taking L = 10 microH we obtain the value of capacitance as C = 2.53nF

The output AM waveform is shown below-
