Semiconductor Photonic Components for RF Applications
Abstract
The objective of this program was to advance the performance of a semiconductor waveguide modulator in external modulated RF fiber-optic links for space-based and airborne platforms such as true time delay beam formation and beam steering subsystems in phased array antennas. Device and material approaches were investigated to improve the modulator based on semiconductor structures for achieving high spur free dynamic range (SFDR) and high frequency operation. In these approaches, the semiconductor optical modulators were specifically designed to achieve high slope efficiency and high center frequency, while with minimal generation of spurious signals. The fiber-optic links using these modulators are expected to satisfy the low noise figure, high center frequencies, low drive power requirements. The following were the main goals in this program: (1) to design and test electroabsorption waveguide modulator for high multi-octave SFDR and high slope efficiency and high saturation optical power operation, and (2) to collaborate with technical personnel at Air Force Research Laboratory at Rome on the overall link design and provide prototype electroabsorption waveguide modulator for link evaluation.
