Study of distributed feedback lasers in reflection configuration

Viac o knihe

The thesis presents a groundbreaking approach to dynamic distributed feedback (DFB) lasers by utilizing a reflection pumping configuration, diverging from the conventional transmission method. It explores the creation of a one-dimensional DFB photonic crystal through transient interference patterns in dye-doped media, revealing index modulation. The study highlights the effectiveness of polarization modulation in facilitating DFB lasing oscillation and introduces a tunable chiral photonic DFB structure that enables circularly-polarized laser output under specific polarization schemes.
