All Products optical MEMSSince 1999 Sercalo Microtechnology Ltd. supplies optical MEMS solutions to the Fiber Optic Industry. Sercalo is the market leader in optical MEMS components for optical Test and Measurement and Network surveillance. Sercalo products, including Fiber Optic Switches, Fiber Optic Attenuators and Tunable Optical Filters, are the solution of choice where high reliability and long-term stability are required. In recent years, new designs of Micro-Mirrors for beam steering and scanning were introduced. Such optical MEMS mirrors are used in Optical scanning Sensors such as Optical Coherence Tomography, scanning LiDARs for autonomous driving and inter-satellite communication to name just a few. 



OPTICAL MEMS FOR EVERY APPLICATIONOptical MEMS are used in a wide range of every day life applications, but also in space, instrumentation, RF applications and many more...

Their broadest use is in the sensor area. There are optical MEMS sensors to measure vibrations, temperature, light, movement (1,2 and 3 axis), linear and rotational acceleration. They are integrated into ink jet printers, video games, cell phones, alarms, cars, etc.

In the medical field, optical MEMS are used as biosensors, pressure sensors, in studies related to drug delivery and other kinds of physical sensors.

In the automotive industry optical MEMS are integrated in intelligent airbags and used in vibration detection and in many other applications. In telecommunications, optical MEMS are used all along the transmission line. Optical MEMS are also used for the implementation of tunable lasers, tunable filters, optical switches, dynamic gain equalizers, attenuators, etc. as it is shown in the image.


Measurement Resource Sharing1. Measurement Resource Sharing

Sercalo optical MEMS switches can be used in measurement environments as a means of resource sharing application. The output signal of a Measurement System is used as the input for an optical MEMS 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 seen from left to right).
This is fully advantageous in the case of automatic testing and in the study of a device's behavior under different conditions all in one measurement.
The activity domain of the optical MEMS 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 optical MEMS switches will also be able to work with visible light expanding the usage to spectroscopy applications.
The main benefits of optical MEMS switches are their high repeatability, with zero recalibration and no wear out

 Line Protection2. Line Protection

Optical MEMS switches can be used in backup environments, in the event of a network failure, or a fiber breakage. In this case, information is transmitted through a backup line. Once the failure has occurred, it needs to be solved in all cases with the fastest procedure. Optical MEMS switches bring the benefit of high reliability and fast response time to this type of scenario.

Remote Network Monitoring3. Remote Network Monitoring

Optical MEMS switches can be used in remote network monitoring. In this kind of scenario, after taking a sample of the light that is being transmitted over the network, the optical MEMS switch will send it to the measurement equipment, for example, a power meter or a Bit Error Rate Tester. In this way, optical MEMS switches can be used to monitor the network automatically and remotely by effectively using the measuring resources and thus detecting a network failure as soon as it occurs.


By Pass Switching4. By-Pass Switching

In this ring using network protection, when a breakage occurs the solution is to send the information to the backup line. But what if a second breakage also occurs in the backup line? In this situation 1 and 2 cannot communicate anymore. In this case optical MEMS switches can be used as a by-pass switching solution. And by placing a 2x2 optical MEMS switch in 3, information can reach 2 from 1. For this type of applications we can highlight the superior reliability of optical MEMS switches.

Measurement Setup5. Measurement Setup

Another application of optical MEMS switches is in measurement setup scenarios. In this case, the switch is used to switch between different wavelengths that are used to test the behavior of the Device Under Test; afterwards a phase of analyze can be done.

The benefits of using switches are their high repeatability, no recalibration and no wear out.

Tunable filters1. Tunable filters

Sercalo 2D MEMS Mirrors are used to fabricate tunable filters. They can be actuated manually or through software, in two different angles (+/-α, +/-β) with analog controls.



Optical Assembly Error Correction2. Optical Assembly Error Correction

Sercalo 2D MEMS Mirrors can be used to correct deviation errors in the input beam. With this correction, the beam can always be adjusted in the first part of the assembly ensuring that all the optical equipment located behind will remain fixed so no recalibration or further adjustment are needed.
