Mems process for optical attenuators

Mems process for optical attenuators

The MEMS attenuator design achieves highly repeatable optical attenuation over C and/or L bands through a thermally-actuated reflective vane that intercepts light. Applications in broadband optical fiber communication system need variable optical attenuators (VOAs) with low wavelength-dependent loss (WDL). Based on analysis on the dispersion of the optical system of a MEMS-based VOA, we provide a method to reduce the WDL significantly with minor revision on. The PM MEMS chip consists of an electrically movable mirror on a silicon support. These products provide the basis for spectrally efficient DWDM transmission utilizing dispersion tolerant modulation, channel monitoring, wavelength switching, remote power control and. The components are characterized with low nsertion loss, fast response and compact size.

Traditional optical attenuators

Traditional optical attenuators

An optical attenuator, or fiber optic attenuator, is a device used to reduce the power level of an optical signal, either in free space or in an optical fiber. The basic types of optical attenuators are fixed, step-wise variable, and continuously variable. The power reduction is done by such means as absorption, reflection, diffusion, scattering, deflection, diffraction, and dispersion, etc.

Low-loss optical attenuators procurement

Low-loss optical attenuators procurement

Explore 43 top manufacturers and suppliers of Fiber Optic Attenuators in our comprehensive photonics buyers' guide. Use this fiber-optic attenuators buying guide to compare major types, define selection criteria, and find suppliers: Professional purchasing of high-value photonics products is a substantial responsibility, where a structured decision-making process is essential. A fiber optic attenuator is a passive optical component designed to attenuate or decrease the intensity of an optical signal traveling through a fiber optic link. Measured in decibels (dB), loss degrades signal quality, limits distance, increases bit-error rate, and escalates infrastructure cost.
