MEMS are nowadays used in a wide range of every day life applications,
but also in space, instrumentation, RF applications...
Their broadest use is in the sensor area. There exist MEMS sensors to measure vibrations, temperature, light, movement (1,2 and 3 axis), linear and rotational acceleration. They are integrated in ink jet printers, video games, cell phones, alarms, cars, etc.
In the medical field, they are used as biosensors, pressure sensors, in studies related to drug delivery and other kinds of physical sensors.
In the automotive area they are integrated in intelligent airbags and used in vibration detection and in many other applications.
In telecommunications they are used all along the transmission line. MEMS are used in the implementation of tunable lasers, tunable filters, optical switches, dynamic gain equalizers, attenuators, etc. as it is shown in the following image.
With the arrival of MEMS, telecommunications knew the all optical network, eliminating the bottleneck caused by the transformation of optical-lectronic-optical signals. As a consequence, it has brought faster transmission speeds and more bandwidth.
Nowadays, research on dynamic reconfigurable routing is being done to make possible changing the network's capacity in function of the demand.
1. Measurement Resource Sharing
Sercalo Switches can be used in measurement environments in the means of resource sharing applications. The output signal of a Measurement System is used as the input of a Sercalo switch which afterwards sends the signal to the appropriate device or fiber, acting in this way as a resource sharing equipment; (the applications can also be also seen from left to right)
This is fully advantageous in the case of automatic testing and in the study of a device's behavior at different conditions all in one measurement.
The activity domain of the Sercalo switches is diverse. Simply by changing the measurement system we change the domain of use, in the telecommunications world an OTDR will be used, in the temperature testing domain a DTS system and in the stress testing a FBG system.
Shortly Sercalo Switches will be also able to work with visible light expanding the usage to spectroscopy applications.
The big benefits of Sercalo switches are their high repeatability, no recalibration and no wear out.
An example of a schematic and possible applications of the Custom Fiber Optic Switch Systems is the following:
1. Tunable filters
Sercalo 2D MEMS Mirror is, between other applications, used to fabricate tunable filters. It can be actuated manually or through software, in two different angles (+/-α, +/-β) with analog controls.
Sercalo's VOAs are used for electronic power management or remote attenuation control. They can also be used for gain control of optical amplifiers in WDM
