Fully Reconfigurable Coupled-Resonator Optical Waveguides (CROWs) with 10 nW Static Power MEMS

Niels Quack, Alain Yuji Takabayashi

We report on fully reconfigurable CROWs with MEMS-tunable waveguides. Resonatorto-resonator and resonator-to-waveguide coupling are fully tunable. Resonance of a resonator is also widely tunable to cover its full FSR. The static power consumption per tunab ...
