Polarization-independent wavelength path switching is demonstrated with one-chip silicon photonic circuit including 64 thermo-optical switch elements within 12mm × 3mm. Owing to uniformity, any path can be constructed by simply turning on one switch element.
The first C and L bands wavelength tunable laser module was demonstrated with micro-ring resonators fabricated with silicon photonic wire waveguides. The hybrid integrated laser is compact and lower power consumption.
A silicon photonic-wire waveguide based wavelength tunable laser was firstly demonstrated; whose micro-ring resonator footprint was 700 times 450 mum. Its wavelength tuning range is 38 nm at a tuning power of 26-mW.
Extremely small wavelength tunable optical add-drop multiplexers and 1 times N thermo-optic switches were demonstrated with high-Si-wire waveguides. These micro-photonic devices with Si-wire waveguides are attractive for constructing photonic integrated circuits for use in future photonic network systems.
A compact 1 times 4 optical switch modules were demonstrated with extremely small thermo-optic switches constructed by high-Delta Si-wire waveguides. The characteristics of the device chip and the module will be presented.
This paper reports MEMS inertial sensor which is based on the principle of a rotational gyroscope can detect both 3-axis acceleration and 2-axis angular rate at a time by electrostatically suspending and rotating rotor in the shape of a ring made from silicon. The device has several advantages: the levitation of the rotor in a vacuum eliminates a mechanical friction resulting in high sensitivity;...
