A range of ion beam techniques have been used to fabricate a variety of photonic guiding
structures in the well-known lithium niobate (⁠ LiNbO 3 or LN) crystals that are of great …

Probing optical properties of materials and optical characterization of crystallographic
defects at the nanometer scale have been inaccessible until recently due to the diffraction …

Diffraction, a fundamental process in wave physics, leads to spreading of the optical beams
as they propagate. However, new photonic crystal (PhC) meta-materials can be nano …

Light-matter interactions can provide a wealth of detailed information about the structural,
electronic, optical, and chemical properties of materials through various excitation and …

An optical probe for photonic integrated circuits is proposed and demonstrated. The device
is based on a single-mode fiber containing a subwavelength period metal grating on the …

Whispering gallery modes in cylindrical integrated optics microcavities have, for what is to
our knowledge the first time, been mapped with a photon scanning tunneling microscope …

Scanning near-field optical microscopy SNOM has attracted considerable attention in the
past fifteen years as a technique to obtain optical images of surfaces with subwavelength …

We employ a collection scanning near-field optical microscope (SNOM) to image the
propagation of light at telecommunication wavelengths along straight and bent regions of …

An inherent problem to the study of waveguides with strong propagation losses by
Scattering??? type Scanning Near field Optical Microscopy is the coherent optical …

By using scanning near-field optical microscopy, we directly map the subwavelength
