Resumo
In this work, a polymer-based single channel trimodal interferometric sensor is presented and demonstrated. The presented device was fabricated with Direct Laser Writer Technique at 405 nm wavelength on SU-8 photoresist, showing free spectral range of 20.2 nm and signal visibility of 5.7 dB, reaching very high sensitivity to temperature variations of 0.058 dB/°C.
