Fabrication of 1.55.$\mu\textrm{m}$ RWG-DFB-LDs and evaluation of its optical characteristics
1.55$\mu\textrm{m}$ RWG-DFB-LD 제작 및 광학 특성 평가
Abstract
We fabricated the 1.55.mu.m RWG-DFB-LD and measured its electrical and optical characteristics. Interference fringe of optical beams was used for grating formation and epi layers were grown by lower-temperature LPE. The fabricated RWG-DFB-LD operated in a single longitudinal mode with more than 30dB SMSR at 1543nm emitting wavelength and its threshold current was 40mA. The wavelength shift with operating temperature and characteristic temperature T
