A 1×6 compound-driven MEMS-based optical device with optical switch and variable optical power attenuating functions has been proposed to optimally serve multifunctional optical fiber-based networking applications. The device manipulates the light with binary-slope mirrors driven by compound electrostatic actuator. The optical models for attenuating are investigated. Performances of the fabricated devices assembled with ball-lensed fibers are measured and discussed. Measurements reveal that the insertion loss of the device is less than 2.7 dB and the controllable attenuation range is more than 40 dB for the switching and attenuation function, respectively.

Splicing fluoride glass fibers and silica fibers is a critical point for manufacturing all fibered laser modules. As these materials are extremely different, various problems must be considered: thermal, expansion, mechanical, chemical. Reliability and power handling make priority concerns. We report splices made on a 200/220 multimode silica fiber and a double clad 15/250/290 ZBLAN fiber. Splices are proof tested at 300 g tensile strength. No damage is observed after thermal cycling from -30 °C to 85 °C, at 40 % RH during 24 hours. Typical optical splice loss is about 0.2 dB. They withstand 220 W input power at 976 nm without any damage and drastic temperature increasing.

In this paper we present three techniques to improve optical power handling capacity of micro-mirrors: (a) improving flexure conduction, (b) improving reflectivity of micro-mirrors and (c) using silicon carbide as MEMS structural material. Mirrors fabricated in Multi-User MEMS Processes (MUMPs) are used as prototype models. It is shown numerically that these three techniques can improve the power handling capacity of the mirrors by factors of 1.25, 4–13 and 7 respectively. Further enhancement can be achieved by using the combination of these methods. Numerical work in this paper was done using Coventorware® while experiments were carried out using an 808 nm center wavelength laser diode with maximum power of 1 W.
