31 March 2005 Polymer-based thermo-optic switch for optical true time delay
Author Affiliations +
A thermo-optic switch using total internal reflection waveguide was fabricated for optical true time delay. Experimental result shows that the crosstalk in the bar state is as low as -42dB and the total insertion loss is only -4dB at the wavelength of 1.55μm. A power consumption of 130mWand switching speeds of 2ms are obtained as well, which makes the device qualified to be used in the application of optical true time delay.
