ABSTRACT:
A sensor and method for page-based optical data storage. The sensor includes a partially-reflective mirror, a reflective mirror disposed substantially collinear with and spaced apart from the partially-reflective mirror, and an active layer disposed substantially collinear with and between the partially-reflective mirror and the reflective mirror. The partially-reflective mirror has a first and second side and transmits a portion of light incident on the first side. The reflective mirror reflects light incident on the reflective mirror toward the partially-reflective mirror. The active layer absorbs at least a portion of the light oscillating at the resonant frequency.
