| Abstract(in English) | Efficient control of millimeter waves in a slot line on Si and GaAs substrate is discussed both theoretically and experimentally. The spectral domain method is used to estimate the propagation constant and the attenuation in the slot line as a function of the density of the optically induced Plasma. Experiments in the millimeter wave range of 35 GHz to 50 GHz are carried out using high resistivity Si and GaAs wafers with the dimension of 15 mm×30 mm×600μm. The slot-width is varied from 0.5 mm to 2 mm. The attention of millimeter waves of more than 25 dB can be controlled by optical means using LEDs with 870 nm wavelength and 100 mW of optical power. The experimental results agree considerably well with theory. The response of millimeter waves with pulsed optical illumination is also examined using a high power laser diode of 20 W optical power and pulse width less than 100 ns. High speed response due to optically induced plasma is confirmed for the slot line on GaAs substrate. |
