Optical Communications & Adaptive Optics

Optical communications:
Fiber optic components in general can be classified, based on their functions, into two categories – passive components and active components. Passive components are those which
only pass on a signal but do not alter the signal’s basic characteristics or transmission format.
Typical passive components include Wavelength DeMultplixers (WDM), isolators, attenuators, amplifiers, couplers, connectors, and optical switches.
Active components are those which process a signal and change its basic characteristics or transmission format. Examples include lasers, tunable lasers, transmitters, receivers, transceivers, media converters, and transponders.
Many active components contain passive components.

Fueled by the demand for faster internet connection and multiservice solutions, investments in existing and new optical network infrastructures are steadily growing to benefit the optical networking industry.
Optical system integrators are looking for proven high quality and high reliability components to be safely integrated in complex optical modules operating up to 100 GBits.

MEMSCAP is a leading supplier of MEMS based passive optical networking subcomponents used in high-speed telecommunications and data communications networks (source Isupply report …).
The company designs, manufactures and sells its own products and also develop solutions with our customers based upon their specific product needs and specifications.

MEMSCAP products are in the passive component category and are usually integrated in more complex sub-systems which then benefit from the size reduction and improved reliability of our MEMS devices.
Among the company's best selling products family are MEMS based Variable Optical Attenuators, with approximately 75% market share. They are steadily gaining momentum and market share over competing traditional technologies in optical networks applications ranging from optical modules protection to the growing segment of Power Management.

MEMSCAP customers include optical component manufacturers, as well as telecommunications and data communications network system vendors located around the world and their contract manufacturers.

Adaptive optics:
Adaptive optics (AO) is a technology used to improve the performance of optical systems by reducing the effect of wavefront distortions. It is used in astronomical telescopes and laser communication systems to remove the effects of atmospheric distortion, and in retinal imaging systems to reduce the impact of optical aberrations.

Given their versatility, the maturity of technology, and the high resolution wavefront correction that they can afford, MEMS deformable mirrors are currently the most widely used technology in wavefront shaping applications. Matching the performance of their large-scale counterparts, MEMS deformable mirrors have been shown to meet the needs of applications such as microscopy, astronomy, vision science, laser beam shaping, and a variety of defense applications.

MEMS deformable mirrors exhibit unmatched performance strengths inherent to the technology itself and the micromachining techniques used. With appropriate design, large actuator arrays provide with high resolution wavefront correction possibilities and large fill factor. High density actuators and weak coupling between neighboring actuators permit high order corrections of the optical wavefronts thanks to the production of high frequency shapes on the mirror surface.
