The TM electrostatic MEMS mirrors are designed for static beam steering and to minimize effects such as drift, hysteresis and temperature dependent performance. These dual-axes mirrors with up to 2.5mm aperture are driven with an electrostatic comb drive at a tilt angle of up to +/-4°.
Electrostatic MEMS mirrors combine the high pointing stability and the high fill factor required typically in fiber optic components. Sercalo uses these mirrors for the SC and TF product lines.
Operating Principle
Sercalo's Electrostatic MEMS mirrors are constructed as a compact chip that combines the mirror surface, comb-drive actuator, and torsion bars acting as mechanical springs. The underlying operating principle is based on the generation of electrostatic forces that move the mirror. The torsion bars both support the mirror and provide a restoring force that stabilizes and limits the rotation, ensuiring precise prositioning.
Electrostatic drive has excellent static performance and is the solution of choice for advanced fiber optic light processing such as in MEMS variable optical attenuators, fiber optic switches and tunable optical filters.
