Radial Bragg lasers: optimal design for minimal threshold levels and enhanced mode discrimination
收藏 引用
JOURNAL OF THE OPTICAL SOCIETY OF AMERICA B-OPTICAL PHYSICS 2007年 第9期24卷 2178-2184页
作者: Scheuer, Jacob Tel Aviv Univ Sch Elect Engn Ramat Aviv Israel
Radial Bragg distributed-feedback (DFB) lasers are designed and studied using the transfer matrix method, allowing an accurate analysis beyond the coupled-mode equations approach (small perturbations). Compared with c... 详细信息

HYBRID QUASI-STATIC ANALYSIS FOR MULTILAYER COPLANAR LINES
收藏 引用
IEE PROCEEDINGS-H MICROwaveS ANTENNAS AND PROPAGATION 1991年 第4期138卷 307-312页
作者: CHANG, CN WONG, YC CHEN, CH Department of Electrical Engineering National Taiwan University Taipei Republic of China
A new quasistatic analysis of a coplanar waveguiding structure with multidielectric layers is presented, using a hybrid approach that combines the Galerkin finite-element method and the conformal-mapping technique. In... 详细信息

Photorefractive charge compensation in α-phase proton-exchanged LiNbO3 waveguides
收藏 引用
JOURNAL OF THE OPTICAL SOCIETY OF AMERICA B-OPTICAL PHYSICS 2000年 第8期17卷 1412-1419页
作者: Méndez, A García-Cabañes, A Carrascosa, M Cabrera, JM Univ Autonoma Madrid Dept Fis Mat E-28049 Madrid Spain
Photorefractive recording and light and dark erasures have been measured in unannealed alpha-phase proton-exchanged LiNbO3 waveguides. The saturation index change, Delta n(s) congruent to 9 x 10(-6), is independent of... 详细信息

PRACTICAL USE OF THE SPATIAL COHERENCE FUNCTION FOR DETERMINING LASER TRANSVERSE-MODE STRUCTURE
收藏 引用
OPTICAL ENGINEERING 1995年 第11期34卷 3323-3328页
作者: PELZ, LJ ANDERSON, BL Univ. of Dayton (USA) Ohio State Univ. (USA)
The spatial coherence function of a beam exiting from a waveguiding device can be used to determine the transverse modal composition of the fields which are supported within the structure. The strength of the spatial ... 详细信息
