With our expertise in optical technologies, we enable our customers to implement smaller, faster, function-rich and cost-effective optical systems.
Silicon Optical Benches
As digital communication speeds increase, laser-to-fiber mechanical connections require increasingly precise alignments and tight tolerances. Effectiveness of optical devices in high frequency applications requires integrated alignment of multiple individual elements.
If your project involves precise optical alignment, a laser optical bench, an optical filter structure or the use of a complex mirror, Teledyne MEMS has a solution.
Partnering with the right fabricator to ensure precision alignment, light coupling optimization and robust manufacturing processes is critical. Such optical devices also require packaging to enable high volume manufacturing at low costs. Our MEMS devices and micro-fabrication expertise provide tailored customer solutions for this application.
Advances in MEMS technology and surface micromachining have led to the development of numerous optical devices that take advantage of micro mirror structures. Our two decades of experience in miniaturized mirrors capable of high reflectivity, rapid actuation and precise movement have enabled countless new applications in optical communications, medical devices, imaging and micro displays to name a few.
Optical elements require fast and precise movement. Products like micro mirrors and light valves use small incremental steps to accomplish tasks like laser beam steering and spectrum changes. To accomplish this precise actuation, designers use various methods to drive structures.
Micralyne has developed several actuation platforms used by our customers to drive optical structures. These platforms take advantage of the Micralyne MEMS and micromachining capabilities like DRIE, thin film deposition and wafer level packaging.
