• Generation of Modulated Microwave Signals using Optical Techniques for Onboard Spacecraft Applications 

  Yogesh Prasad, K R (2017-12-01)

  This thesis deals with optical synthesis of unmodulated and modulated microwave signals. Generation of microwave signals based on optical heterodyning is discussed in detail. The effect of phase noise of laser on heterodyned ...

• Effects Of Spin Polarization And Spatial Confinement On Optical Properties Of Bulk Semiconductors And Doped Quantum Wells 

  Joshua, Arjun (2010-04-06)

  We correlated experimental results with theoretical estimations of the dielectric function ε(ω) in two contexts: the effect of an electric field in quantum wells and that of the spin polarization of an interacting electron-hole ...

• Experimental Studies Of Electron Spin Dynamics In Semiconductors Using A Novel Radio Frequency Detection Technique 

  Guite, Chinkhanlun (2015-08-05)

  A novel experimental setup has been realized to measure weak magnetic moments which can be modulated at radio frequencies (~1–5 MHz). Using an optimized radio-frequency (RF) pickup coil and lock-in amplifier, an experimental ...
