Distributed Raman optical amplification in phase coherent transfer of optical frequencies

, 2012
We describe the application of Raman Optical-fiber Amplification (ROA) for the phase coherent transfer of optical frequencies in an optical fiber link. ROA uses the transmission fiber itself as a gain medium for bi-directional coherent amplification.

Fiber-diffraction Interferometer using Coherent Fiber Optic Taper [PDF]

, 2010
We present a fiber-diffraction interferometer using a coherent fiber optic taper for optical testing in an uncontrolled environment. We use a coherent fiber optic taper and a single-mode fiber having thermally-expanded core.

Nanoscale coherent imaging of photonic structures by PSTM [PDF]

, 2000
We present an alternative instrument to map local optical field distributions: a photon scanning tunneling microscope (PSTM). In a PSTM a near-field optical fiber probe is used to frustrate the evanescent field above an integrated optical device.
