Abstract
A tunable filter with a flattopped passband is provided for use as a micromachined optical filter with input and output optical fibers which provides a wavelength tunability with several discrete wavelengths and a flattopped passband. The standard Fabry-Perot resonator is modified by incorporating multilayer dielectrics to form a pair of interference filters, one of which is vibrated to provide for tunability and provision of several resonant wavelengths. The layers can either be deposited on an existing dielectric slab of a Fabry-Perot device or included on the ends of the input and output optical fibers which are then incorporated into the Fabry-Perot device.
