High Differential Group Index of Dispersion Compensating Fibers for OCDMA Encoder/Decoder
《光学学报》2003年第S1期221-222,共2页Tae-Jung Eom Chang-Soo Park Un-Chul Paek Byeong Ha Lee Taesang Park 
We report the LPG pair device that can be used as a pulse duplicator or an OCDMA encoder/decoder. Due to the ring core region of dispersion compensating fiber (DCF), we can shorten the device length by a third and obt...
