In this thesis, for the first  time, dynamic DFB lasing action was achieved in a  reflection pumping configuration instead of the  traditional transmission pumping one. A tunable one- dimensional (1-D) DFB photonic crystal (PC) created  by transient interference pattern of two crossing  pump beams was obtained in dye doped laser media,  which indicated the existence of an index  modulation. The polarization modulation, realized by  readily manipulating the state of polarization of  the pumping beams, was demonstrated effective in  providing feedback for DFB lasing oscillation in the  reflection pumping configuration. A tunable chiral  photonic DFB structure was observed in certain  polarization pumping schemes, which can be  identified as a dynamic polarization dependent  chiral PC. Tunable circularly-polarized laser output  was obtained.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783838397986\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783838397986","offer_id":39493567250525,"sku":"9783838397986","price":79.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/3df05b33-3594-442e-bea2-7b0406cc9d36.jpg?v=1757655829","url":"https:\/\/shop.autorenwelt.de\/en\/products\/study-of-distributed-feedback-lasers-in-reflection-configuration-von-fei-chen","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
