Measurement of internal spatial modes and local propagation properties in optical waveguides
نویسندگان
چکیده
Internal spatial modes and local properties controlling optical wave propagation have been measured in glass/silica buried waveguides. The period of the observed standing modes provides a direct measure of the local effective index. The measured effective index and transverse modal shape determines the values of all components of the wave vector. In addition, we describe a technique that can obtain detailed information about the locations of remote dielectric interfaces. © 1999 American Institute of Physics. @S0003-6951~99!05042-1#

Near-field scanning optical microscopy has been used to measure the internal spatial modes and local properties controlling optical wave propagation in glass/silica buried waveguides. The period of the observed standing modes provides a direct measure of the effective index, which combined with the measured transverse modal shape and decay constants, determines the values of all spatial compone...

We have used near-field scanning optical microscopy to measure the internal optical modes inside glass waveguides and microring resonators. The period of the observed standing modes provides a direct measure of the local effective index. The measured effective index and modal shape determines the values of all components of the wave vector. The observed standing modes inside the ring resonator ...
متن کاملNear-field characterization of propagating optical modes in photonic crystal waveguides.
We analyze the propagating optical modes in a Silicon membrane photonic crystal waveguide, based on subwavelength-resolution amplitude and phase measurements of the optical fields using a heterodyne near-field scanning optical microscope (H-NSOM). Fourier analysis of the experimentally obtained optical amplitude and phase data permits identification of the propagating waveguide modes, including...
متن کاملA Novel technique to measure propagation loss of optical waveguides
A method to measure the propagation loss of optical waveguides is discussed. The measurement system involves two 3 dB couplers, a CCD camera and a signal processing unit. The propagation loss measured from this technique is found to be independent of coupling conditions. The propagation properties of waveguides prepared by proton exchange (PE) in Lithium Niobate (LiNbO3) and Silver ion exchange...
متن کاملPolarization-resolved imaging of an ensemble of waveguide modes.
We demonstrate polarization-sensitive measurement of the modal content of waveguides by generalizing the classic rotating wave-plate-based polarimeter to wide-field optical low-coherence interferometry. The spatial phases of the modes are retrieved with principal component analysis. By applying this polarization-sensitive cross-correlation (C2) imaging technique to the characterization of a few...
