US Patent 7924413 - Nanowire array resonator

http://www.freepatentsonline.com/7924413.html

This patent from HP teaches a way to fabricate light sensors and modulators with nanoscale dimensions based on semiconductor nanowires. Claim 1 reads:

1. A nanowire-based device comprising:

a reflective member;

a resonant cavity at least partially enclosed by the reflective member; and

at least one nanowire disposed within the resonant cavity, the nanowire including at least one active segment selectively disposed along the length of the nanowire to substantially coincide with antinodes of light to resonate within the cavity, the active segment to interact with the light to resonate within the cavity.
