Abstract
In one embodiment, a system for determining information about an assay incorporates a filter assembly that includes an optical structure configured to be removably attachable to a laser resonating cavity of the system, the optical structure being configured to form a portion of the laser resonating cavity such that it reflects light propagating through a gain medium in the laser resonating cavity when attached thereto. The optical structure can include a first surface having an array of one or more sites, each site containing an assay, and a second surface configured such that the second surface is disposed within the laser resonating cavity forming a portion of the laser resonating cavity. The optical structure is configured to optically interact with the assay to change one or more characteristics of light in the laser resonating cavity based on a reaction that occurs in an assay on said first surface.
