Abstract

We report our progress on integrated phosphorus-doped SiO₂ optical waveguide delay lines and membrane optical routing switches for phased-array radar control. We have completed the design and layout of the delay lines for the two shortest bits. We have demonstrated the concept of a microelectromechanical membrane optical routing switch with a Mach-Zehnder interferometer and a fixed aluminum thin film. Channel crosstalk values as low as -12.4 dB and -20.3 dB were measured with and without a 3 mm aluminum film, respectively. We have designed the membrane structure for the switch to have better yield, improved reliability, and lower excitation voltage.
