We have experimentally demonstrated feedforward and recirculating FPPGAs with MEMS-tunable elements. The static power of the elements is less than 50 nW, and energy required to change the state of the actuator is 8 pJ.

We propose and demonstrate an ultra-low-power 3×3 unitary matrix multiplier with MEMS-based tunable couplers and phase shifters. The static power consumption and tuning energy per tuning element are less than 0.13 µW and 115 pJ, respectively.

We develop a novel nanocomposite electrolyte, consisting of yttria-stabilized zirconia (YSZ) and erbia-stabilized bismuth oxide (ESB). The 20 mol% ESB-incorporated YSZ composite (20ESB-YSZ) achieves the high density (>97%) at the low sintering temper

We present an arbitrary 8×8 beam pattern projection system based on a programmable grating coupler array with a Fourier lens. The static power consumption and the reconfiguration time are below 1µW and 10µs, respectively.
