Near-field scanning optical microscopy of standing waves in fiber Bragg gratings
Near-field scanning optical microscopy (NSOM) can provide direct information about the electric fields inside optoelectronic devices with subwavelength resolution. This letter describes direct, wavelength-resolved measurements of the amplitude and phase of the standing waves within a fiber Bragg grating, using a heterodyne interference variant of NSOM that works at telecommunications wavelengths. The amplitudes of forward- and backward-going components of the standing wave can be measured separately, and the position shift of the standing wave antinodes as the wavelength varies across the stop band is imaged directly.

Abstract

Near-field scanning optical microscopy (NSOM) can provide direct information about the electric fields inside optoelectronic devices with subwavelength resolution. This letter describes direct, wavelength-resolved measurements of the amplitude and phase of the standing waves within a fiber Bragg grating, using a heterodyne interference variant of NSOM that works at telecommunications wavelengths. The amplitudes of forward- and backward-going components of the standing wave can be measured separately, and the position shift of the standing wave antinodes as the wavelength varies across the stop band is imaged directly.
