Abstract:
1. A tunable laser assembly, said assembly comprising: a laser that is a source of energy; a highly reflective bottom mirror; a convex mirror; and a guided-mode grating resonant filter, said guided-mode grating resonant filter pivotably mounted between said laser and said mirror, wherein at least some of said energy from said laser impinges upon said guided-mode grating resonant filter, which is configured to direct at least some of said energy upon said convex mirror, which is configured to direct at least some of said energy back to said guided-mode grating resonant filter, which is configured to direct at least some of said energy back to said laser, which is configured to direct at least some of said energy through said highly reflective bottom mirror, wherein movement of said guided-mode grating resonant filter relative to said laser varies the wavelength of energy emitted from the laser.
