Paper Abstract

A nanosecond pulsed laser deposition at room temperature was used to fabricate a waveguide of Sic:Ge:Fe . The waveguide was used as an optical sensor to detect the sound wave disturbance under water. It was observed that the HeNe laser drives the optical sensor to produce multiple diffraction rings, which are affected by the sound wave disturbance to produce unique clusters of rings with elongated shape pointing away from the source of the acoustic waves. It was observed that, the shape of the rings resonance with the waves to produce either constructive or destructive interference pattern which produce the elongated shape. The Sensor has the same results if it is driven by either HeNe laser or Ar ion laser. The optical characterization of the sensor's performance under harsh environment will be presented as well.
