Planar MEMS Variable Optical Attenuators (VOAs) with Linear Attenuation-Voltage Characteristics
(IEEE, 345 E 47TH ST, NEW YORK, NY 10017 USA, 01.01.2019)
Variable optical attenuators (VOAs) are essential components in wavelength division multiplexing (WDM) networks, light waveform generators, and optical fiber test equipment. Among various types of planar MEMS VOAs, a shutter ...
Quasi-Static Operation of 2-Axis-Tilt Microscanners with AlN Piezoelectric Quad-Actuators
(IEEE, 2021)
Aluminum nitride (AlN) started to draw
attentions as a material for piezoelectric actuation owing to its
CMOS process compatibility and safeness for biomedical
applications. Due to its relatively low piezoelectric ...

Design of Wide-Band Tunable Optical Filters with Cascaded Microring Resonators and Shaped-Finger Comb-Drive Actuators
(IEEE345 E 47TH ST, NEW YORK, NY 10017 USA, 2016)
Utilizing the Vernier effect, series coupling of multiple microring resonators with different sizes is used to design a wide-band (free spectral range: 36 nm) tunable filter. For index modulators that shift the filter ...
Symmetric Electret-Based Vibration Energy Harvesters with Curved-Beam Hinges
(Institute of Electrical and Electronics Engineers Inc., 2023)
Broadband power spectral characteristics are
desirable in vibration energy harvesters, and it can be achieved
by employing curved-beam hinges, which exhibit forcedisplacement nonlinearity. Via numerical analysis by ...
