Silicon photonic MEMS phase shifter with mu s time constant built on a foundry platform

Niels Quack, Alain Yuji Takabayashi, Hamed Sattari

MEMS enable low power tuners in silicon photonics, but existing phase shifters lack in range, speed, and loss. We implement a 2 pi phase shifter with a 1.54 mu s time constant and 0.5 dB insertion loss in IMEC's iSiPP5OG platform. ...
