The Transmission Spectra of Phase-Shifted LPG and Its Application in OADM
Based on the coupled-mode theory, the transmission spectra of the phase-shifted long period fiber grating (LPG) are stuided. The imapcts of the inserted phase number, apodized function on LPG spectra are discussed in detail. A new scheme of optical add drop multiplexer (OADM) configuration based on cascaded phase-shifted LPG filter is proposed for flexible multiple wavelengths add-drop.
