Cavity resonance shift and bandwidth enhancement in semiconductor lasers with strong light injection
Publikováno v:
IEEE Journal of Quantum Electronics. 39:1196-1204
We theoretically investigated the physical mechanism of significant bandwidth enhancement in injection-locked semiconductor lasers with strong light injection. Strong light injection can increase the semiconductor laser bandwidth to several times the

A new method of analysis called the partial-boundary element method (p-BEM) is proposed for the analysis of striplines with arbitrary cross-sectional dielectric in multi-layered media. By using a Green's function that satisfies the boundary condition

The propagation and dispersion characteristics of picosecond electrical pulses in a suspended coplanar waveguide (SCPW) are investigated, and it is shown that the SCPW is a very promising transmission structure for ultrashort pulses. Numerical result

A new modal analysis method based on the combination of a point-matching method and a group theoretic approach is proposed by which optical fibers having symmetrically distributed multiple cores on a circumference can be studied. The case of sextet c

The propagation and dispersion characteristics of picosecond pulses in a suspended coplanar waveguide (SCPW) are presented. An evaluation based on numerical analysis shows that the SCPW can result in an improvement of about five times in pulse transm
