Abstract :
We demonstrate the generation of continuous wave terahertz radiation from Fe-doped InGaAs and Fe-doped InGaAsP photomixers grown by Metal Organic Chemical Vapor Deposition (MOCVD), using a pair of 1550 nm diode lasers. A bandwidth of > 2.4 THz is obtained from the emitters and the effect of doping on emitted power and bandwidth is studied.
