Dispersion Compensating Fiber Module
... To impel the progress of DWDM transmission system, there are two requirements for improving the performance of SC-DCF modules. The first requirement is a lowering of insertion loss of the SC-DCF module in optical fiber transmission systems. Low-loss SC-DCF module contributes to the relaxation in opt ...

... What does a trapped Bose-Einstein condensate look like? More precisely, how does it interact with light, and does this differ fundamentally from what one would naively expect from a similar collection of very cold atoms? In the early 1990s, before Bose-Einstein condensation was realized in atomic ga ...

Vertical-Cavity Surface-Emitting Lasers: Advanced
... An important contribution of this thesis is the novel concept of chirpassisted coherent detection for direct current modulated VCSELs. A coherent receiver approach that exploits adiabatic frequency chirping of direct modulated VCSELs to improve the extinction ratio of received signals is introduced. ...
