Research abstract
The goal is to develop a tunable differential interferometer for wideband phase-to-amplitude conversion. The device must have high-optical power handling (> 300 mW) and low loss (< 3 dB) to ensure the creation of low-noise figure, high-dynamic range RF-over-fiber links. The device should operate over a -40°C to +85°C operational temperature range, and be tunable to cover phase-to-amplitude conversion from 1 GHz on the low end to 45 GHz on the high end, with an instantaneous operational bandwidth of at least one octave, with tuning speeds over this range on the order of < 10 ms. The device should have dimensions no greater than 1 cm height, 10 cm long, and 3 cm wide. Individual devices should be designed to operate in 1 µm wavelength and 1550 nm wavelength RF over fiber links.
