With the view of that, the laser with optical injection-locked structure is proposed to enhance speed performance by use of adding resonance frequencies in semiconductor lasers. However, this structure needs an external injection from other laser cavity, resulting in huge cost, and inconvenience. In spite of it, in this thesis, we demonstrate a novel InAlGaAs-MQW Fabry-Perot laser with the structure of monolithic optical injection. It can enjoy the advantage such as single chip package, needless of optical isolator or circulator, automatic optical alignment, and environmentally robust. The device can achieve high resonance frequency at 41GHz, and comparing with non optical injecting, directly modulation bandwidth has twice improvement to 20GHz. en_US DC.subject 光注入式 zh_TW DC.subject 高速 zh_TW DC.subject 半導體雷射 zh_TW DC.subject semiconductor laser en_US DC.subject optical injection en_US DC.subject high speed en_US DC.title 兩段整合光注入式1.55μm高速半導體雷射 zh_TW dc.language.iso zh-TW zh-TW DC.title High-Speed Two Sectional Integrated Optical Injection Semiconductor Lasers at 1.55μm Wavelength en_US DC.type 博碩士論文 zh_TW DC.type thesis en_US DC.publisher National Central University en_US
