MEMSCAP Achieves Milestone in Supplying Variable Optical Attenuator MEMS Chips

MEMSCAP has announced that over the last few years, it has supplied over one million MEMS-based thermally actuated variable optical attenuator chips.

MEMSCAP is a provider of MEMS-based optical products and solutions with superior reliability and performance to the optical community. MEMS-based variable optical attenuators are used in complicated optical modules running at up to 100 Gb. Their market share is ever-increasing over competing conventional technologies used in optical network applications such as optical modules protection and power management.

MEMSCAP introduced die level tests in February 2011 for the thermally actuated MEMS variable optical attenuator product line, thus corroborating that the MEMS devices run under all specifications even beyond 200 millions cycles. Taking advantage from its optical MEMS IP in design and production, the company has designed several thermally actuated variable optical attenuators in normally closed and normally open configurations, which include various die shapes, sizes and attenuation specifications to meet demands of customers.

In the fiscal year 2011, MEMSCAP unveiled several variable optical attenuator dies utilizing electrostatic actuation, working under low or high voltage. The company’s variable optical attenuator dies are ideal for most of the existing packaging technologies and they demonstrate higher optical power attenuation stability in close loop mode. The company offers its complete suite of electrostatically and thermally actuated optical attenuators for both sampling and production shipments.

According to Jérémie Bouchaud, IHS iSuppli’s Director and Principal Analyst for MEMS and Sensors, MEMSCAP ranks the first place in supplying optical MEMS chips for use in variable optical attenuators used in optical telecommunication market.
