Nanomechanical Photonic Devices

US Patent:
2011010, May 5, 2011
Filed:
Apr 9, 2009
Appl. No.:
12/920631
Inventors:
Hongxing Tang - New Haven CT,
Mo Li - New Haven CT,
Wolfram Pernice - New Haven CT,
Chi Xiong - New Haven CT,
International Classification:
G02F 1/01
G02B 6/35
G02B 6/26
G01N 21/84
US Classification:
385 1, 385 13, 385 25, 356 731
Abstract:
The present invention relates to devices which operate on gradient optical forces, in particular, nanoscale mechanical devices which are actuable by gradient optical forces. Such a device comprises a waveguide and a dielectric body, with at least a portion of the waveguide separated from the dielectric body at a distance which permits evanescent coupling of an optical mode within the waveguide to the dielectric body. This results in an optical force which acts on the waveguide and which can be exploited in a variety of devices on a nano scale, including all-optical switches, photonic transistors, tuneable couplers, optical attenuators and tuneable phase shifters. The waveguide can also comprise a gap such that two cantilever bridges are formed.
