Photonic modulation of a photonic band gap
First Claim
Patent Images
1. An apparatus comprising:
- a first photonic crystal structure having a first photonic band gap distribution and configured to support a first electromagnetic signal having a first frequency distribution, the first photonic crystal structure including a first mechanically movable element;
a first converter configured to receive a second electromagnetic signal different from the first electromagnetic signal and having a second frequency distribution that does not overlap the first frequency distribution, wherein the first converter is further configured to output a first electrical signal corresponding to the second electromagnetic signal; and
wherein the first mechanically movable element is responsive to the first electrical signal to change the first photonic band gap distribution.
