Near-forward scattering of an optically trapped 5-mum-radius polystyrene latex sphere by the trapping beam was examined both theoretically and experimentally. Since the trapping beam is tightly focused, the beam fields superpose and interfere with the scattered fields in the forward hemisphere. The observed light intensity consists of a series of concentric(More)
Whispering gallery modes in microspheres are excited by light delivered to them via optical fibers imbedded in a half-block coupler. The corresponding light intensity resonances in microspheres and coupling of two low-order linearly polarized modes in the fibers, LP₀₁ and LP₁₁, into the microspheres are observed. The LP₀₁ and LP₁₁ modes are delivered to the(More)
Since its founding, NASA has been dedicated to the advancement of aeronautics and space science. The NASA Scientific and Technical Information (STI) Program Office plays a key part in helping NASA maintain this important role. The NASA STI Program Office is operated by Langley Research Center, the Lead Center for NASA's scientific and technical information.(More)
