Micro‑Opto‑Electro‑Mechanical Systems (MOEMS) development (Mechanical Engineering) VILNIUS TECH

Overview

Compact, narrow‑band optical devices for the infrared (IR) range can be fabricated using conventional silicon micromachining techniques specific to microelectromechanical systems (MEMS). These approaches allow critical parameters—such as filtering or reflection bands—to be tuned by modifying the lithographic design. Fabricated down to the device layer of silicon‑on‑insulator wafers, these miniature narrow‑band optical structures will be tested for integrated operation within confined spaces, with a focus on exploring their absorption and reflection characteristics.

The successful candidate will participate in research on the applicability of this innovative technology platform for integrated IR sources and detectors. Specifically, micromachined bridges and/or arrays of such structures are promising for broadband IR generation and pyroelectric detection. The outcomes of the proposed research will contribute to the development of highly integrated and cost‑effective multichannel optical sensors capable of analysing a wide range of materials with unprecedented cross‑selectivity and sensitivity.

The candidate will also be encouraged to join subsequent stages of sensor development, exploring the potential of integrating IR optics with MEMS to enable flexible adjustment of absorption and reflection parameters. We expect that the techniques investigated by the successful candidate will not only exhibit improved overall technical performance but also demonstrate the potential to reduce the cost of IR‑based detectors for various organic and inorganic materials.
