| Abstract: | 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. |
