This paper proposes a circuit topology which reduces the chip size of single-pole–double-throw (SPDT) quarter-wavelength bandpass filter-integrated switches (FIS). A 40-GHz mHEMT MMIC SPDT switch has ...

We demonstrated an extremely low power consumption thermooptic switch using suspended ridge and silicon-silica hybrid waveguide structures. The switching power was successfully reduced to only 0.6 mW.
