Contactless Measurements

We present the development of an interferometer capable of making contactless measurements of vibrations. The resultsshow the we achieve micro- and/or nano-metric measurements without the stabilization of the laser. While there aremultiple techniques to achieve this objective, in this case we use a method whose main virtue is the low componentcount and the self-alignment capacity. The method is based on the optical feedback effect in a laser diode which relieson the use of an internal reference for calibration.

Chaos synchronization of delayed quantum dot light emitting diode has been studied theortetically which are coupled via the unidirectional and bidirectional. at synchronization of chaotic, The dynamics is identical with delayed optical feedback for those coupling methods. Depending on the coupling parameters and delay time the system exhibits complete synchronization, . Under proper conditions, the receiver quantum dot light emitting diode can be satisfactorily synchronized with the transmitter quantum dot light emitting diode due to the optical feedback effect.
