Abstract
A novel tuned coupled-microresonator filter with a known transfer function. This transfer function may be used, along with the filter's output signal, to extract the original input signal. The quality factor of manufacturable microresonators typically exceeds 106 and permits the attainment of exceptionally high resolution in a small, physically-rugged, environmentally-protected package. In addition, the properties of the resonator and coupling optics lend themselves to low cost production.
