Abstract
Influence of distance between two coupled strong-confinement photonic devices on optically resonant condition thereof and/or on optical forces.
Claims21
An optomechanical system comprising:
- a first strong-confinement photonic device (SCPD);
- an optical input port optically coupled to the first SCPD;
- and
- a second SCPD optically coupled to the first SCPD and movably positioned with respect to the first SCPD,
- wherein (i) at least one of the first SCPD or the second SCPD comprises an optical resonator, (ii) an optical mode excited in the input port induces an optical force acting on the second SCPD, and (iii) at a first distance between a location in the first SCPD and a location in the second SCPD, the optical force points towards the location in the first SCPD, and, at a second distance between the location in the first SCPD and the location in the first SCPD, the optical force points away from the location in the first SCPD, the first distance being greater than the second distance.

An optomechanical system comprising:
- a first photonic device comprising (i) a first strong confinement photonic structure (SCPS), (ii) a second SCPS disposed at a fixed position with respect to the first SCPS, and (iii) an optical input port optically coupled to the first SCPS and the second SCPS;
- and
- a second photonic device comprising (i) a third SCPS optically coupled to the first SCPS, and (ii) a fourth SCPS disposed at a fixed position with respect to the third SCPS and optically coupled to the second SCPS, the second photonic device being movably positioned with respect to the first photonic device,
- wherein (i) an optical mode excited in the optical input port induces a first optical force between the first SCPS and the third SCPS and a second optical force between the second SCPS and the fourth SCPS, (ii) the first optical force is attractive and greater in magnitude than the second optical force at a first distance between the first photonic device and the second photonic device, and (iii) the second optical force is repulsive and greater in magnitude than the first optical force at a second distance between the first photonic device and the second photonic device, the first distance being greater than the second distance.
