Sabeus proposes to build and demonstrate a High Speed Electronically Tunable Fiber-Optic Filter based upon the Penn State ARL design. The filter consists of a Long Period Grating (LPG) coated with an electro-optic polymer. An applied voltage varies the refractive index of the coating surruounding the LPG to tune the filter wavelength. The filter will be tunable over a 50 nm range with a nanosecond tuning speed. For this effort, Sabeus will design and create the LPG, and Penn State ARL will apply the EO coatings.
Benefits: No current source exists for a tunable optical filter with a nanosecond tuning speed. The anticipated benefit will be a compact, rugged, and reliable optical filter for military and commercial telecom applications
