High Q Fabry-Perot resonators have been achieved using only polymeric materials and lamination process. The resonator is fabricated by two plane parallel Bragg mirrors, commercially available (3M), composed of hundred layers with alternating high- and low-index layers of polyester and acrylic polymer with a high reflectivity (R>98%). The cavity, the mirrors and the substrates are assembled by a cold lamination process. This approach simplifies the fabrication procedure while retaining high optical surface quality, resulting in a compact, low-cost disposable device. Depending on the mirrors reflectivity, FP resonators with quality factor up to Q=180000 and finesse of F=486 have been fabricated.
