Electro-optical Materials: Efficient Poling of Electro-Optic Polymers in Thin Films and Silicon Slot Waveguides by Detachable Pyroelectric Crystals (Adv. Mater. 10/2012)



original image

This first ever Advanced Optical Materials cover design shows a silicon–polymer hybrid slot waveguide ring-resonator modulator being poled by two pyroelectric crystals. Each of the three images, from top to bottom, indicates one stage of the poling—before, during, and after—with the device configuration in the front and the dipole alignment state represented in the background. For details on how this was achieved, check out the article by A. K.-Y. Jen and co-workers on page OP42.
